I've been reading on so far, what the fuck. Are you guys not microing with your crawlers, and are you forgetting of the crawlers best buddy and partner. The bomber, one bomber is all it takes to kill a squad of archidon, ONE BOMBER (I've witnessed this bullshit countless times, and it has thwarted me countless times further)! And all it requires is for the order player to mess up and for you to keep the art surprise (If they don't know you have a bomber then you might just surprise them). AND the crawlers aren't the only things you have in that massive arsenal of chaos (its the same amount as order but you get the point) Theirs more units than just crawlers. Deads have 3 bars of health and are armored, they can fuck up archidons and with poison guts they can fuck up even more. They also deal armor piercing damage last I remember.
Now if your using only crawlers (apparently that's all I got out of the main page) then instead of going with the classic 2 crawler 2 miner scheme which everybody knows buy this instead. 4 crawlers and 1 bomber, then use your first income gain from the miners to buy 2 more bombers and then from their on you have your crawler defense/offense, your anti sword defense/offense. And if your lucky and don't have to use all of your bombers then you can store em away for later when they are truly needed, Pressure your enemy into buying castle archer and you have just gained a huge economic advantage.
There is one thing I agree to though, castle deads need an upgrade, turrets can help but not fully kill packs of low tier units.
Now back to crawlers, they heal pretty god damn fast if you ask me. And if I remember correctly they run just a little faster than swordwrath and attack faster, but this complaint is about damage well lets take a look here, predatory edge is meant to increase the speed of them for last I remember 100 gold and 50 mana and pact something is meant to increase the damage of them for 200 gold and 100 mana yes? Pact something increases the damage of crawlers by a small amount for each stacking crawler all the way to five crawlers total. Now its obvious crawlers were not meant to fight alone, they are supposed to be those units where power comes in teamwork. Now if crawlers are WAY more under powered than I last saw them then one suggestion that will work for everybody, Decrease the cost for predatory edge from whatever it was before down to 50 gold and 50 mana, and pact something down to 100 gold and 50 mana. Rage does both but comes at a longer time, usually right when the swordwrath are either no longer bought or are out tier'd by juggerknights and eclispors/speartons and albowtross.
Now 4 swordwrath on what I'm guessing is the map called castle, times will be tough but chaos can pull through in the map called castle with 4 crawlers and 3 bombers, it will get the swordwrath out of your hair due to their cheap cost and quick reload time.
Now you may be saying "WELL KING what if he gets the classic archidon and 4 swordwrath match, then my 4 crawler and 3 bomber will cease to exist!" Well lets see here, the bomber is MUCH faster than the archidon and one shot from the archidon doesn't kill a bomber (Fuck you bomber, ERM I MEAN HALLELUJAH), and if you just so happened to have not gotten something more then , if the bomber is protected by the crawler then chances are the bomber could kill the archer even if the archer is using backwards kiting, the swordwrath you can take on with the remaining 3 crawlers and if the archidon did not manage to kill a bomber then 2 bombers (chances are that archidon killed one of your crawlers with backwards kiting) and if things look bad retreat in the scrap then send the wounded crawler back to base, it will run and slowly regenerate as it runs to garrison. CHAOS'S AUTO HEAL IS THERE FOR A REASON, to regenerate health from wounded allies, now chaos's auto heal is not as effective towards higher tier units (NAAW really king?) but towards units such as the crawler its heavenly fast when not in combat (now still it does heal you while in combat but your losing more health than you are regenerating, its helpful but its not OP or UP).
Now I think I've made my point on my standing and what I think. Crawlers are good if you pair with a bomber, but they need their upgrades to be decreased in price. Turrets can HELP but not kill, castle deads need something like a damage increase or a major decrease in cost all together along with prioritizing units who are not poisoned over the rest. 4 crawlers and 3 bombers are the magic numbers when it comes to defense against 4 swordwrath, but you really shouldn't rely on them to save you forever... Eventually stronger units are gonna come and your gonna need heavier fire power. Crawlers are hit and runs, not fight till the ends because the end is gonna come quicker than you think for crawlers. Swordwrath > Crawler, don't use JUST crawlers. Crawlers are not main army if they aren't accompanied by bombers. Swordwrath < Crawler and bomber most of the time, I mean it will get them out of your hair but your really gonna have to do some targeting and pressuring, also strike fear into them with three bombers, three bombers can kill a group of swordwrath and if I am wrong then 4 bombers can kill a group, swordwrath need to group in order to effectively kill. I'm not saying that grouping is required but targeting is a major thing for swordwrath. I would know since they are huge part of my early and late army.
BY THE WAY, I just realized something. Where's the replay of this incident happening? Surely you must have a replay if you want us to get a full picture on what the problem is and for us to decipher whether or not its just you complaining that this guy bested you or if there is a serious problem even when you used your crawlers in the art of micro.
