If graves is broken...

because his damage and tank is to high, and he can be played anywhere effectively and efficiently.

Then can we please finally nerf !!!!! he has literally been doing this exact thing for months, the only difference is that he has more than just a slow, he also has a stun, his consume (effectively a kalista ult that trades knock up for damage). He builds health for damage, then also gets almost double effective health because of his E. His ulti gives him two skills, a tf teleport (with friends) and a better version of shen's passive. Point is, he gets a lot of better versions of skills that already exist on other champions.

Seriously if riot was going for a support champion who was on par with thresh they accomplished it. Instead of the absurd amounts of utility thresh brings, tahm bring about half as much, and then trades the rest for insane scaling.

P.S. Thresh is also broken, just it's utility power rather than stat power.
