@Iffem I think, in a special mode, there will be champs that OP (like the banned one) while some are terrible (like Mundo in URF). There are reasons that mode is not permanently. About the useless passive, it's like in a collection. Some parts are non-valuable but you can't finish a collection without them.

@VirusVirus Yeah, thanks for pointing it out. There will be some group of passive that you just can pick one.

@VuLinhAssassin That's one of the problems I found if doing this mode. Some passive uses animation that others model may not fit (like how a normal champion turns into a Kog'Maw running around or the revive passives).

Anyway, this is a fun mode. It's hardly for this mode to be in LoL. If Riot does this mode, I think lots of players like this.
