I've lowered Ruin's damage, increased its cooldowns at all ranks, gave Jaunt an ammo system, a damaging passive which scales with level rather than rank and a health scaling on Blitz to give players incentive to build tanky now (which should in turn reduce the damage capability of a fully charged Ruin, making it clear that Jaunt's passive is the primary damage source for Zar'Kas).

Hopefully these changes adresses the issues you've stated with Zar'Kas, such as low cooldowns, too much burst damage for a tanky character, no definite primary damage source, etc.
