Does Genji need help?

Huge issues with mitigation and healing output have curb his effectiveness dramatically. He was never good with Tanks, specifically, but the additional mitigation brought about because of mandatory secondary tank makes it just that much harder for him to deal with things.

There’s not much that can be done right now. OW2 should more or less put him back on even ground and that will hopefully fix some problems.

Quoted for emphasis. Though keep in mind that this post from the patch date is ancient and the metagame has shifted quite a bit.
