Charges- The ability to cast the same ability with a separate cooldown. For example, If I have two charges of kick. I can kick once and I can kick again right after then each kick has its own cooldown.
The reason for this is to give an extra layer of combat and an extra layer for devs to buff and nerf skills. There are many skills that could use this. Also, PvE and PvP could easily be more split this way. PvE has 5 charges of a skill vs. PvP having 2 charges. No damage needs to be changed, no cooldown has to be changed.
Venoms could be changed so that it has 5 charges of 1 venom attack. instead of 5 venom attacks and 1 charge for more control. Long cooldown skills like Consecration skills, could use 2 charges each(or when traited).
