Grounded Debuff of Morde's W

Hey guys, I have some ideas for Mordekaiser buffs: We all know that his W is so unreliable. E.g. a Nidalee is ganking you, and in that moment you want to heal of her she just jumps away, or when u want to kill a Trynda, he spins away, you can't catch up because your Stormraider Mastery is on Cooldown. I have this problem so many times, that I couldnt punish x-champion for fighting me. So how about putting the grounded debuff on mordekaiser's W when the circles overlapp. It would really help him in teamfights, too, because then, he can focus mobile ADCs better.

And speaking of Mordekaiser buffs, how about this: When Mordekaiser uses his E on a Target who has his ult on (who is cursed) the E ability has a special bonus.

It can: slow the target/stun it/deals more dmg/heals Morde/pulls Target back to Morde (kinda like Kled's Q)/gives morde more shield/gives or steals MR/etc.

I love playing Morde, and I know he's not that great, so some buffs would be nice.
