In Everquest, experience potions already exist and are on occasion available from mobs, quests, and the trading card game as a loot item.

There is also a veteran reward available that allows you to get double experience for 30 minutes, once a day. It's commonly called the death buff. It seems whenever you use it, you die.

In any case, they are not introducing anything that is not available already in the game. Fancy graphics and pets and 1 charge potions.

I don't see it as a big deal. I've played EQ since beta (98) and this doesn't bother me at all.
