In mid tier you can go str, or go more tanky - all depends on your personal preferations and game style, at that lvl your dmg is not that much behind others... gap is huge in T4 - there go wounds/toughness 2h utility / support tank.
Tails should be defensive like armor bonus/ toughnes even its 2h?
Your dmg can never match other tanks there... So no point trying.
p.s. Only thing worth taking for crests at this point is sc weapon.
