Mage against Berserker - no chance - MODERATORS - do something - Overpowered Berserk

no worries ... wait till all gets to higher BR and main become a useless meat shield anyway

statistics and build trend seems to agree. with the main the only one having the dodge boost from passive skills, being the tank or shield is its best position in the long run. unless they bring out a new hero that has a high block and dodge percentage

mage is powerful. Sorcerer class has that Fireball skill that ignores def, partner skill that bleeds 10%hp for 2 turns, the third skill reducing hit. All you need to do is 10-11k dodge, 11-12k hit.
Mystic class has low dmg, but use your main as tank, boost in dodge, block, hp, END, with fair def and mdef, then recruit damager heroes like claw and amazon. Mystic class can boost your heroes' hit.

assuming you have all mythic equips, it will just decide on how much luck you have on activating those mythic equips' skills like the dmg reduction of helm and boots, stun from ring, rage reduction from greaves.

try learning from old servers first, check builds of old but active players, coz most of the servers have mages on top.
