Returning after a long break. Why is /thf no longer viable compared to /sam and /war?
Are you the one that posted on my (Ranzear) Youtube video? Whether or not... Welcome. There's much for you to learn here.
/THF provides no real increase in damage except for Sneak Attack. Trick Attack has precisely zero value when hate caps so readily on anyone and everyone and tanks are worthless until such is remedied.
One critical hit on one quarter of your WS every 60 seconds is laughable. I can WS five times a minute with a particular weapon. You're 100% better off with Seigan and Hitbuilding on /SAM, Berserk and Double Attack from /WAR, or even the now minute-recast jumps and a free 5% haste on /DRG.
