A perfect team has 2 or 3 bubblers at the moment. And they are very hard to lock down.
LoL really thats some serious shi tty team.
You know bubble puts a debuff on the receiver right? You can have 15 sages in your ops group, and you can still only be bubbled once every 17-20 second.
Talking about clueless. You should only take 1 bubbler that know how to play that's it or 2 at most.
Some people can be seriously clueless. Btw properly specced hybrid bubbler has very low bubble force cost and no CD on the bubble, (because again it's hard capped by the debuff).
