Another Diana rework
Ironstylus put that "Rework Diana" topic up a few months ago, and I didn't try anything then, but I think I've got something rough right now.
The idea is to change out Diana being an assassin and remaking her into an AP/AS fighter who does DPS rather than good burst. Right now, there's no Champion who I'd call a magic-type melee carry, so Diana could fit the bill.
Here are some rough ideas for new/modified skills (take them with a grain of salt).
P - Moonsilver Blade
Same as before, but grants higher amounts of AS at level intervals. Some of the base damage and possibly AP ratio should be reduced to compensate, making it better in a DPS-fashion rather than burst.
Q - Crescent Strike/Lunar Rush
Merged together Diana's live Q and R in a Lee Sin-esque fashion. First, you use Q as normal, which then lets you use Lunar Rush with Q once within the next 3 seconds. HOWEVER, you can only target enemies hit by Crescent Strike, meaning you need to land that ranged shot first. Reduce Crescent Strike's damage and put some of it into Lunar Rush (which should be adjusted in damage since it will be a normal skill instead of an ultimate) to require Diana to take a risk if she wants to deal the greater part of the damage.
W - Pale Cascade
Same as before. Good skill, nothing needs changing.
E - Lunari Fervor (NEW!)
New skill: For X seconds, Diana gains increased attack speed and magic penetration. Kills and assists reduce the cooldown.
R - Moonfall
Moonfall is now Diana's ultimate, has a larger AOE, and also deals magic damage along with its other effects, which are upgraded since it will be an ultimate. Cooldown is drastically increased.
Again, these are just rough ideas, but they might start something. Any comments?
