Yorick needs nerfs

This is getting ridiculous, a SUPPORT yorick does stupid damage. I regularly get triple kills when jg comes to gank bot and can usually 1v1 the top laner on a support budget. I can push 3 lanes at once. I can solo herald. I can duo baron with pretty much anyone else. I can provide excellent peel if my adc knows how to use the wall to kite, and the higher elo i get the more i see adc's doing this right. I completely shit on any melee support and any ranged support (except brand, this is the only matchup that is unwinnable if the brand knows what he's doing) as well if i take my move speed runes. No adc except cait has a chance at fighting vs me and my adc and winning. I can block people off from getting through choke points, forcing them to go around or sink 4 autos into my wall. A well timed wall keeps people from stealing baron, drag, helps take towers, peels for adc, traps enemies. I can push down several towers on my own. I often create more pressure than the rest of my team combined, sometimes ending games in 15 minutes. I don't know of any other support with this much impact. Even thresh is weak compared to this in terms of impact and play making. I always go relic shield asap and if I need more to protect my adc I get locket. I can split, WHILE GROUPED. I can even play the poke game with e max into redemption if I need to. All of this together makes me think the following.

I'm only gold 4 and higher elo players might be able to shit on me, but at this elo this is not ok. My suggestion is to nerf yorick ult. The extra magic damage on hit is simply broken and needs to be lowered.

EDIT: ok nobody believes me, whatever, I'll just continue to abuse this with no repercussions since nobody else plays yorick.
