"...it might not be as easy for people like me, who struggle to last hit with mages."

The irony here is that you gave the description in the innate "ally," not "allied champion." This means you don't even need to last hit since minions and turrets are also allies.

One thing that can be done for Rejuvenation is that affected allies received increased healing from all sources for X seconds, while Necrius would receive double that amount. Otherwise, amp up that healing a bit, since Necrius has it on a long enough cooldown, a 5 second channel and also use Essence.
