Warwick and Malzahar rework? (at least their ults)

So lately I've been seeing more and more Warwicks and Malzahars, and for good reason: They have some extremely powerful kits with a lack of counterplay.

Malzahar is very oppressive in lane and can shove like no one's business. The fact he gets mana back from it as well is extremely powerful and doesn't have any counterplay. During a 1v1, he insta-wins any duel due to his ultimate. His ultimate is a click suppress for an extremely long duration, and if he's a decent malzahar, he used all of his abilities as well, securing a kill.

Warwick isn't much of an improvement. Asides from whether he should have good sustain, his Ult and Blood Scent lacks counterplay as well. His ult is a click suppress, and deals a ton of damage if you have a couple on hit effects. This can bring squishies to low health, which then makes him near impossible to escape from since blood scent both GIVES SIGHT of weak champions and a great movement speed buff.

Now there's Quick Silver Sash to counter both champions, but it also is problematic in itemization and price: It delays your final build by a lot (1550 gold) and for APCs, doesn't build into any damage items. It feels kind of crummy to buy if you are already behind as is, meanwhile they just get to build more damage.

Simply put, both champions need some counterplay to their ults. Right now, they are top tier duelists due to the lack of good counterplay.
