well a couple of major problems

1) you didnt change the two things that are most often talked about needing a change on her, specifically her P/AS and Q. the low base AS makes it hard to build AS as you get less from it, and her Q is really good poke large aoe making it hard to dodge and low mana cost, which helps her before she has her ult so struggles to go in.

2) the changes you did make will turn her into a bad xin, well tank xin anyway and with low ap scaling forcing her to go tank and her ult doesn't need resists as she can pick up zhonyas. moving her r to e means she will either be a massive lane bully jumping on your face 24/7 with Q-R-W-AA till W reapplies then back out, it also takes away her biggest weakness early, no mobility.

i think the biggest problem is you focused on her initiate, which is fine on diana anyway, and to do this you took away a lot of her assassinate and AS/AP bruiser (or left it weak). if you want to play a champ with this play style (but a better kit for it) play xin.
