You've given an example and not a definition; could I have a definition?
Something that gives you a massive advantage over your opponent(s) with little effort on your part.
The Spearton's effectiveness as a defensive unit doesn't match the Juggerknight's ability as an offensive unit. The shield (push?) ability is only effective if the opponent chooses to directly engage the shield-walled Speartons. Otherwise the attack's range is too small.
Compare this to the Juggerknight's charge ability. It is guaranteed to hit an opponent in front. Oh, and you can attack whilst doing it. To utilize the shield bash you need to be not even attacking.
The effective range of the shield bash, is I believe(could be mistaken) just higher than that of the attacking range of the spearton. I believe you and I define defensive differently. I define it as, sit back and wait in a fortified position. Water against the rocks if you will. For this, the spearton not only serves this purpose, he does it painfully well.
When we also consider that a Juggerknight against a Spearton results in a win for the Juggerknight (something you've not addressed), this tips the balance is Chaos' favour even further.
As someone said, Chaos plays aggressively, order plays defensively. Chaos is to attack, while Order is to counter.
So not only will you be getting a Spearton, you'll also be researching rage, and obtaining a swordwrath?
It was an example. An Archidon could most likely kill the Juggerknight at how low the health would be after an encounter with a Spearton. The point of me saying that, is because you continue to say, the Juggerknight is massively overpowered compared to the Spearton, and yet, as I just said, 1-2(maybe 3-4) shots from an Archidon could save the Spearton, and kill the Juggerknight. Also, I don't research rage.
Whilst this Chaos player has just one Juggerknight? Again, can we please not assume the opponent has the IQ of a lemon. What is this Chaos player doing with the extra gold and extra time?
Normally, they are building up a larger army at their base, or at the middle, while also building up their economy. It's a poker thing, why show everyone your entire hand, when you can show them one card, and let them guess?
And why are we assuming that the Juggerknight will keep the swordwrath alive for the whole duration of the battle? Again, we assume our opponents are lemons.
See, now you're assuming the Order player is a lemon(why a lemon? Why not a lime or an apple?), he could easily have the Swordwrath attack once, run back, attack again, run back, or hand back for a while OR attack and when he gets too injured, retreat it?
The castle archer costs. When we consider the small income we have in the beginning, this is not a "minimal" loss to Order, and if it is, this "minimal" loss is unbalanced towards Chaos.
300 For an Castle Archer, and if the chaos player is stupid enough to let his units die, that would be 200 lost. With that being said, the effectiveness of the castle archer no matter the stage of the game, more than makes up for it.
I'm sorry, I should've put that request differently.
Give me one situation in which the Chaos player does not play like a lemon, and the Shield wall is still more effective than attacking.
I was giving an example with order vs order. Well, let's see, if you have the Speartons just a tiny bit being the wall(Yes, I said wall the first time) and the Juggerknight's charge will have no affect on the Speartons, while the Speartons are open to use shield-bash and stun them, then eat their faces(I'm a fan of zombies). WHY LEMONS AGAIN.
Your example lacks validity in that no decent Chaos player would giant spam when they have a whole arsenal of offensive units to use. Not to mention that the giants would simply stroll past your Speartons, meaning that they'd be better off attacking the giants.
Walls, They can't go past the walls. The Speartons are only meant to be there sitting back for a few moments, while the Magikill & Archidons do some damage.
