sry, there is a huge difference between Diana and LeBlank.
Many times, I ended up facing feed leblanks as Diana due to me getting camped. But as soon as I hit 2 items, that leblank was melting.
LeBlank does a lot of single target damage with her QQW combo. Or a lot of AoE burst but not really targeted with QWW.
Diana is different. Diana does BOTH, single target and AoE burst is a small area. Also, as I mentioned above, the combo that I use for Diana is R first. Why?
Because me, and most Diana players will generally prefer to hit Q first for R reset, then go in. But that's different, Diana DOESN'T HAVE TO hit Q first. She get R first to guaranteed that W and Q will also land.
Another huge difference between the two is that LeBlank can't wave clear. Diana can help with wave clear as her Q is ranged.
And as far as split pushing. Diana is BY FAR the better one at taking down turrets or even objectives.
However, LeBlank has very good poke and very good mobility. This is what Diana lacks and is what sets these two assassins apart.
As far as "bruiser" Diana. Its a highly ineffective playstyle. As such, the majority of Diana player do not adopt it. And I don't believe its nice for you to try to force it on us (don't worry, riot will probably do the same thing).
Also, you made 1 more mistake. You think Diana wants to use her E to push people away. Its the opposite. She wants EVERYONE GATHERED TOGETHER, so her W explodes for massive damage. Also more targets to hit with Q at a once.
Look, your intention might be good (give bruiser Diana a chance). But you are doing that at the expense of assassin Diana. And that's the Diana I'm maining (Even though I don't really matter since I'm semi retired/quit). Almost every other Diana player plays her as an assassin. That means brusier Diana is not popular so you will only hurt the mains by nerfing the assassin Diana play style.
Ps, my standard build for RWQ combo is nashors, lich bane, void staff. It would require me to give up nashors for echo to one shot targets with Diana. If it were for your changes to happen.
And giving up nashors means giving up split push power and team fight dps after I 1shot the enemy carry
