no luck needed with def. Why do you think def is so nerfed? 1 str for ex. gives 1 att but less than 1 def it's because it's to OP. this is exact why komamura is only van with def oriented talent(it gives 15% to def kido def and immunity) and skill, give it to someone with better base stats and growth rate and you won't need anyone else in pvp.
yer your saying u have 5x komamura ?... bottom line is tank dont do well.. they just get stun, slient, etc until they die lol... and def on attacker make them less of an attacker lol... i mean heck all my attackers have dodge/block/counter 90% lv10 stam with break def, crit 90% too.. but guess what? any attack who atks first mob the floor with me clean so yer good luck my tank the only who lives but he get rape after 4 rounds of constant stun
