PvP Boss mode idea

So this idea was spawned off the thought "Imagine in the Piety fight you could use her portals"

Now expand that to a PvP mode where portals randomly pop up in the arena that transform you into a boss for 10-15 seconds.
Obviously bosses rebalanced to be equal level.

Imagine, Vaal vs Piety.

I really like idea like this. Objective pvp is fun. I like some staging but also a open box. Would be cool to see something like a capture the "goblin" or something. I like the boss fight idea tho. Would be cool to also have different bosses with a base that maybe teams competitively fought to kill the boss captain sorta like DOTA lol.

This would also create alot of diversity in builds and more dynamic fights than the pvp we currently offers with 1v1s being the majority of pvp.
