I'll make this simple for you guys. Morde + a non-traditional support sans Leona. Morde + Shen, Morde + Trundle, Morde +Voli, Morde + Garen.. Profit. W is his best skill for two reasons.
- Wave clear... pushing power.
- Jungler triple kill bait. The Aoe DMG+Heal can bait the enemy into thinking it can kill your low HP supp or you. Cast W wait as long as possible and activate the execute.
Warwick ulting Morde's support is only a good idea if their health is low. Morde can still cast W and proc Q plus his ult. Warwick putting himself in a standstill position on most occasions will end badly.
