On one side yes against some classes barbs might tank well.
But then again a class like mystic who will struggle with barb can hiero my wiz for example 123...
I dont know...lowering barbs defense so they get beaten helps what? I reached mystic today 1 time in the whole fight, only thing that saved me is the def. Without a certain tankiness barbs get perma ccd and dont survive it. Not fair against some classes since they have barely a way out of cc.
Wizard and venos have such an easy time against barb, restrict even more def gears means one 0def = insta hiero, same with wizard spark.
I guess you gotta accept not to be able to beat every class or build, same as not every class or build will be able to reach you/kill you easy.
The problem with duel...yes its there and i have no fair solution to it.
Some classes are maybe not really meant to kill each other. Such as barb and blademaster for example, both more of a tanky class. Unless 1 goes full offensive its just not meant to have a winner. It will be impossible to force a winner in some situations, unless you make it full attack gears and sacrifice most HA classes getting 1shotted then by spark, 0def or mystic perma cc...
