WOW Gold: I would rather spend a few minutes finding a buffer, and then having 360 or 720 buffs
Skill Selection: Now, again, there are three options. You have...
1) Buff/Heal - This is definitely the most common skill selection, I pretty much always do this, just so you can get in more parties, and you can get WOW Gold exp a lot faster...not many people want a rezzer in a party... and 960 heals is enough to get you by, until Eslant.
2) Heal/Duff - This is the second most common, once you're higher up, you can 4 stone rezz, which can come in handy...and the 1920 heals and full heals can come in handy sometimes...but not as much as buffing, EVERYONE needs a buff. Pots can replace heals =)
3) Rezz/Heal - Although this is definitely my favorite skill selection for PK, it really isn't used much; it's sooo hard to exp... Most people who do use it, it's their secondary char, so they just have it there to rezz them when they need it.
Now, you may wonder, why no Duff/Buff, or Buff/Duff, well, to be straight up honest, it's usless.
I don't know why people would put buff as a secondary; I would rather spend a few minutes finding a buffer, and then having 360 or 720 buffs.
The only time I run into this, is for people like my clan leader, whose rezzer is Rezz/Buff, so he can get the 720 or 960 buff when he's solo'ing, along side the Rezz's.
