Make the Beta Slot a Permanent
I doubt that 800 getms would be enough to satisfy anyone, there really isnt anything they can do to satisfy anyone, people will always complain because it is easy to do, and sadly, among video game forums, it is far more socially acceptable.
That said, if they are introducing a new class, it isnt a reasonable request at all to get a free character slot so the people might enjoy it withut having to pay on top of the expansion.
And even with that said, I am not upset that people wont get a new slot, because if they did I would have no doubt that the entire population of Tyria would be Revanent.
Buy Ultimate or fork up 800 gems. ANet’s most likely answer.
