Remove Poison Plea for priests

As a few players have suggested, we think the solution here is just to make sure that hunters and rogues aren't so good versus priests simply because of the lack of poison removal. We don't think that needs to be giving Abolish Poison or the like to priests.

There was a pretty hefty nerf to Viper Sting recently. It should be much less of a priest killer.

Q u o t e:
I imagine the dev's feel like the rise of hunters is a MUCH bigger problem to priests then rogues, probably for 2 reasons:

1) Rogues have been around for a while and priests succeeded before, so the drop in priest representation in 2s has more to do with the hunter rise than rogues.
2) A common complaint of people who can dispel poisons (such as me on my shaman) is that even against rogues who leave the totem down, the application rate is too fast to get out of crippling. Thus, if other healers still succeed despite rogue poison application rate, it's probably a lot less rogues and a lot more hunters.

Yes, that is pretty close to how we feel. Poisons are a weakness of the priest class. We don't want to remove that weakness. However Viper Sting exploited that weakness to a very punishing degree. Poison removal, as many other classes will tell you, does not solve "the rogue problem" and I'm not sure there is "a rogue problem" any longer.
