Slight Katarina Buffs Post 6.4@Meddler @Riot

In 5.6 you nerfed Katarina's base health, and base health regen

-Base health regen decreased to 4.5 from 7.7.

While she does have a more decent lane phase now, I think it would be nice to buff her health regen to 5.5-6 health instead of leaving it at 4.5 which feels pretty awful in lane. It isn't a huge buff that will throw her over the top, but I think it will place her in a decent spot where she will be able to survive against poke mages and her zed match up for just a little bit longer. I would also like to propose her E getting a slight buff from the nerf it received in 3.01

• Damage reduction duration reduced to 1.5 seconds from 3.

Could we change it to a flat 2 seconds or even 1.75 giving her a tiny bit better feeling when she has to do a decisive all in?

These are just slight buffs that would feel good playing Katarina in lane and also during the explosive mid/late games we have, allowing her just a slight better edge on her all-ins, while I don't think these are too frustrating of buffs I may be wrong so please leave your comments and ideas!
