Xypherous, Can you take a look at Quicksilver Sash?? It's great because it can remove stuns and CC (taunts, slows, etc), but it shouldn't remove suppression.

Quicksilver Sash was added into the game in the same patch as Suppression was added to Warwick and Malzahar. Previously, their ults could be cleansed (as they were just stuns), but it left them self-stunning and not doing damage.
Suppression was added so CLEANSE would no longer affect their (and Cleanse was eventually changed to just cleanse CC effects only, not debuffs+CC). At the time, WW and Malz ults were the only two Suppression effects in the game.
QSS was added to give players an option to build in counter to Suppressions and negative debuffs like DoTs/Morde ult.
If QSS were to be made unable to cleanse suppression, it would have its purpose covered by a summoner spell and no longer really be needed in the game -- with the exception being to counter DoT effects like Mordekaiser's ult.
