Well. Im speaking of lvl 30s.I dont know how bad these tanks were, but i assume that better than average, atleast 3 of them, because they were from Golden League team afterall.
Berserkers are thinking 10 left clicks and shield braker, Tank-s are thinking 5 left clicks and shield slam. Good berserker will gonna know that and be ready for this, same as tank.
If tank will not get berserker on the ground, then there is nothing to do. Distance is the key
Its pretty much, Berserker vs Tank=Easy , Berserker vs Inquisitor=Hard , Tank vs Berserker=Hard , Tank vs Inquisitor=Easy , Inquisitor vs Berserker=Easy ,
Inquisitor vs Tank=Hard .
Anyway, this game is teamplay based.
There is not strongest class or whatsoever. Every class have advantages and disadvantages against another class in different situations. Anyone can be the best.
Its not the class, its the Master.
