As small of a change as the Diana E change...

As a Diana main of 317 games, I had a 58.6 win rate with Diana. After the changed to Diana's E my win rate dropped to 57.4 and continues to plummet. Fair? Maybe... But I find that the purpose of Diana in a team game is to dive in and E rather than her old "assassinate". Having no E to disengage after engaging and it being solely engage only means that either Diana kills the entire team in one swoop (impossible) or dies trying. I mean changing her E to an just seems so stupid to me. I used to build and have a lot of success. Now i feel like I'm playing and my whole purpose is to be the fight starter. I have more success after the E change with than my old build. This feels wrong to me on so many levels. I've gone from an assassin (who riot calls a diver) to a tank.

If this is the point riot is trying to make then fine but I think that her kit would need to change from its current state to reflect this.
