I created a whole new Skill Tree System. Every Hero has 12 Skills from which he can maximate 6 Skills. The last 2 other Buttons are saved for a Team Up Skill and Ultimate Power Skill.
Medkits are deleted. Heros now Regenerate 1-5% Life per Second. The more you invest in Health the more you regenerate per second. Also there are now 2 Skills included which give Defense Buff or Heal.
Left Mouseclick ist saved for Basic Attack while the Right Mouseklick is saved for Basic AoE Spenders. The other skills all have cooldowns which are the same on all Heroes.
