Yorick Maiden A.I feedback, and a small request

So ive recently picked up Yorick and started to main him after realizing how sleeper OP is he really is. But i wanted to talk about the maiden A.I and maiden in general. The request i have is simple i noticed that when you have the maiden out besides you and you lvl up your R too tier 2 at lvl 11 the maidens HP stats don't upgrade after putting in the point you have to wait till you summon the maiden again which doesn't feel right because i have to wait for the cool down and everything to get my moneys worth for putting that point at lvl 11. That said i was watching a coaching video, and the guy was coaching a diamond 5 Yorick game and he sent the maiden near the end of the match to split push bot and after taking the inhib (Tier 3 was gone.) the maiden suddenly went mid past tier 3 and 2 which weren't even taken yet and went to tier 1 and started attacking it !! here is the video link https://www.youtube.com/watch?v=C9fIC08JvnU it happens around 33:00 in the video. Like seeing it with my own eyes man that was some strange shit LOL but yeah i still feel like the A.I needs to be improved and looked at thanks.
