+1 for dropping SAM in 6.1.
I'm a tank main anyway but having one of the only DPS classes I still enjoy get these sorts of changes is going to have me scurrying back to GNB for the rest of the expansion until they arbitarily come for us too. Frankly they can keep the potency changes and they could make SAM the worst DPS in the game for all I care, but by removing Kaiten they've seriously impacted the feel of the class and that's the dealbreaker for me, but I'm also one of those insane players who actually enjoys managing buffs and resources.
