Jayce Bugs (5.11)
So I noticed a couple of glitches going on with Jayce since patch 5.11 where he got his buff. First, if you target someone to attack them while in Cannon form, then switch to Hammer form right before the auto attack animation starts, you will do a ranged auto attack as if you were still in Cannon form, but it still DOES apply the additional damage. This one isn't too bad. The 2nd one I noticed however is a little more impactful. If you use Hyper Charge while in Cannon form, then switch to Hammer form, you maintain the 100% attack speed (which is normal) however your next 3 auto attacks will deal 0 damage (the first auto will still apply the additional damage from Hammer form, but ONLY the additional damage) once you've auto'ed 3 times or once Hyper Charge wears off, you begin applying damage normally with your auto attacks again. Dear Riot, please take notice of this! <3
