Yup, we're keeping it simple, executive decision. I plan to be fair and generous on leveling - I mean, it's not fair to have someone kill eight mooks in one sentence and have another kill only three but in way that really creates an experience. Does that make any sense? Anyone is free to disagree, I'm all for different points of view. I haven't decided on how the Skill Tree system will work since it's a bit early but yes, we will get new skills and even upgrades to current ones; that's the reason why I didn't go all out with naming my melee skills, i have plans for my own skill tree. xD

EDIT: Let's stick to % and hope everyone is fair. I'm fairly laid back but if I start to see abuses that become a detriment to the experience of other players, I'll make a comment on it.
