ive seen lots of people do different things to capture the middle tower. But which stratergy do you normally use to capture it? Mine is to simply get a swardman and a acherdon. but I see the slaw:
2 swardman: can kill my swardman quite easily, and force my acherdon back
spearton: same thing, just takes longer to train since you need mana

so which stratagy do you normally use?

actually sword archer > double sword (select sword when low on health and hit g, then proceed to kite his sword)
if spearton then get 2 more sword and ur ahead.

i use archer ...a bit risky like u said but once it success, its worth.
against chaos i use the same strategy but with meat shield(s) against miner-miner-miner-castle dead strategy.
against cralwer, just get archer and follow by swordwrath after have a steady economy.
against jugger..same as against spearton (not ya way but same as my way against spearton).
against ninja... hahahaaha mass swordwrath-archer or go ninja vs ninja...need lots of works. but once the opponent ninja is dead, ya have a bigger edge over the battle.
