Shen players, don't panic.
This has been circulating around:
Shen - Likely nerf target. Tough case because he's out of line specifically for organized teams (not just in pro, though that's the most visible case of course). Currently looking at pulling power out of his ult which is where the difference in effectiveness for those different contexts lies with ongoing discussion as to what changes we could make to make him closer to balanced for both solo queue and organized teams at the same time.
However I also saw this:
make the shield scale of the ally's missing hp maybe?* We've actually got exactly that in testing :).
I think I might like the new ult scaling, if the shield values become larger than they are now. Right now since damage creep is so highit doesn't take much for one person to rip through Shen's shield and kill his ally before the channel is even complete. The shield needs to be much bigger to compensate because ulting before the ally takes aggro is no longer going to be as effective.
Or, you know, lower the base ult values and make it scale off HP FFS.
