Wampa is really a mini time bomb nuke like Nihilus. He needs time to build up, but once he lets out his first roar and has additional crit chance and offense, he is pretty dangerous. This is why we need a Hide-the-Wampa team, similar to the Hide-the-Nihilus team, for the Wampa to shine.
I run my Wampa with a double tank team - GK and Old Ben. CLS zeta lead to synergize with Old Ben, and Nihilus as an additional source of damage, in case Wampa gets taken out. Pretty effective team which can take out any team on auto (CLS lead, zBarris, etc). I have remained in the top 5 overnight since I started running it.
