Shen and Spirit Blade
So Riot says that they are going to fix the hit box for his taunt, and I am grateful for that.
The Spirit Blade is still a clunky and unreliable mechanic with long delays after casting a spell and it's far too easy to avoid. I have yet to be hit by an opponents spirit blade, it too easy to position away from it, and I find it hard to land mine. All the opponent has to do is not stand between you and the blade.
I personally would like to see the Spirit Blade removed, but since that's a likely as getting the old Shen back. I believe that Riot needs to change the mechanics to improve its use. A much faster response time, a shorter leash, or a better way to control its position would be great. Something other than casting a spell, and putting yourself on a long CD (W,E) or in an offensive hole (Q). Its necessity to Shen's kit being successful is very high, but its reliability to connect is extremely low.
