Diana is a diver with no magic pen in her kit at all
Every single other diver either has true damage or armor shred. Diana is super hard countered by
because it will block her q preventing moonlight from hitting the target. Theres no way around it. Also
super counters diana because once she is in there is no way out. I realize you cant just give diana magic pen, that would make her op. But if she had maybe witts end or something built into her passive and reduce damage elsewhere it would make a world of a difference to diana players. Another thing is that when diana uses her e she should gain armor and magic resist for each enemy pulled it. Honestly diana is not a diver at all. Idk why riot classified her as one because diana is not a brusier at all. The way that everyone plays her is as an assassin. The higher rank i get with her the more players start to hard counter her. With the recent change to her e (cutting off her ability to escape) she is stuck in the midst of battle durring a teamfight and 9 times out of 10 will die because her R,E combo is now far too powerful for her to even try to land a q. Then what... diana sits there and auto attacks hoping to live long enough to proc her passive or hourglass then die? As a diana main I can honestly tell you that there is a very low skill cap to diana. I hope that in the future riot realizes this and can change some of the things in her kit to work with the constantly changing meta. She is very outdated at this point considering there hasent been any item changes that benifit diana in a long time.
