Master Yi Alpha Strike Gameplay

I don't know if anyone else has had this problem but when playing yi there are a few bugs. The first and biggest is the reset at dragon. If you are soloing dragon and you alpha strike as yi dragon will soft reset, sitting back on the ground then knocking you away again when you finish your alpha strike. This can be frustrating as it removes one of your hardest damage spells from dragon making you lose out in terms of dragon clear speed versus other jungerls that can cast their spells, i.e. pantheon, vi, sejuani. The other bug that I would like do discuss with his alpha strike is his untargetability. I'm not sure if this was programmed this way but when you alpha strike you are still able to be hit by non target aoe spells, i.e. annie's W, Malzahar's pool, and last but not least sunfire's effect. If this was intended please clarify so as everyone can understand the reasoning. These have been going on for the last couple patches and I would like to see them fixed.

Thank you for your time, Avatre
