3* Boosts

Wish there was some way to trade these in for 4* boosts. Never use the 3* boosts anymore unless there is a specific 3* arena to grind. Since the change in arenas these things seem really useless.

I just end up saving them for item boost objectives and use a whole bunch for points there.

Yeah, most people just save them for the 3* specific arenas. Would be cool to have a trade-in system or something though.

Trade-in for 5* and/or 6* arena boost.

The time it takes to activate the boosts plus the game loading lag make it not worthwhile to go out of the way to activate them lol
