I started as a shaman, and while I’ve been enjoying it as my main class for this season and in all other forms of wow. I just am reaching a point where shaman is a bit of a barrier to entry. Most groups only want 1, or 2 depending on melee count. I imagine when it comes to level 60 raids its going to be difficult to get in.
Depends on a lot of factors. Generally how easy you are to get side tract and how good you are at being efficient. As well as if you are questing or dungeon grinding (or having a awesome guildie boost you for free) or a mix of both.
However its quite fast as you have that 150% increase to exp until 50, then 50-60 is 50% exp increase.
Personally I’d recommend questing and doing a dungeon when you gather all (or most) of its quests and if you cant find a group ask if a guildie will run you through for that juicy dungeon quest exp.
Also you should do the incursion dailies at the appropriate level brackets as the rep gear will help alot once u hit 50.
