If you don't use potions you're being an absolute *bleep* you your healers in endgame. Even in raids like CT and ST, potions to top yourself off so your healer doesn't have to is common courtesy in my eyes. But hey ho let the healer pick it up right? If we wipe it's their fault <if you can't tell that was a cheap try at sarcasm>.

BTW guildheists teach brand new mmo players how to heal, how to tank and how to gtfo of the aoe. But still people make the same mistakes. Such is life eh?

Anyway pots & food are always needed. If you ain't using endgame you need ro have a quick chat with your FC.
