Currently single tank is strong on his own (always was) but their numbers multiplied and now they are the main choice of all classes on both battle and siege server. Situation on siege is worse than in battle but I have to say I've never seen so many pure str tincans in "new" cRPG. Seems to me that many people have more gold than they need.
Atm. cRPG is nerfed version of 2010. cRPG with ranged being nerfed a lot (mostly archers, xbowmen and throwers are almost the same) and ton of tincans.
Lets not exaggerate, there are many more melee str builds yes, but still relatively few full str tincans. Maybe because a build such as 24/15 with 69 armor is more efficient in battle than a full str plate build.
