Most MMOs you begin with at least one basic ability. Having to do multiple kill quests right off the bat where all you do is watch your toon slowly swing a weapon with no impact is a huge turn-off and might get the game uninstalled before even giving it a chance.
The point of my post is to recommend, if you did not plan on it already (I know this is alpha) at least a basic skill or two for someone to press. It's a small thing but I really believe it matters.
You have Auto attack the start and get your other abilities while leveling up :)
