I know it may be a sort of tradition that a new expansion adds another class or race to the list of playables but, do we really need another race or class so soon after the introduction of the Pandaren and the Monk class?
MoP is still less than a year old and judging by the timescale Blizzard have been sticking to over this expansion, it could very well be the shortest lived expansion yet.
One of the big things that came with MoP was the amount of effort Blizzard were going to just so that we could have 1 extra character slot on servers. So that people who already had 10 max level characters could be happy that they wouldn't have to delete any or have to start fresh on another server just to play a Monk. There was also talk of somehow allowing players to have access to all their toons on one server. So it would in effect allow players to have all 50 possible toons on the same realm and they could all benefit from heirlooms and the gold that is sat there in your main's wallet/purse.
At present, we have 13 races and 11 classes. At what point does it become too much?
Don't get me wrong though, I love the diversity and would love to play an Arrakoa or Ogre or hell, a Furbolg would be cool for me. But really, a new race with another new racial and another class brings more balance issues. And eventually, you're going to run out of meaningful races/classes to add to the playable roster. Of course, Blizzard could quite easily make some lore up on the spot to make things like Naga or Tol'vir playable.
I think I'm starting to ramble now... so, do we really need a new race/class added in the next expansion? Wouldn't it just be better for Blizzard to focus on story and gameplay, making them the main reason people buy/play the new expansion (which is likely Legion based so I assume loads of people will want to see how that plays out and doing a second rate job on it will just irk people to no end)?
Would love to know what everyone thinks. Though from all the threads about what race or class is next, I feel I may get shouted at :P
