I don't really get the point you're trying to make. Maybe clarify? Fusion is one of the very few ways in the game to get guaranteed champions. Why is it a waste of time?

the way it is set up  i have only got one legendary champion(1 only)  and there is only three epics that is it.some  of the three epics  can be obtained by shards.  the fusion doesnt allow you to get  enough legendary champions, i have plenty of fusable champions to fuse together but have only got 1 legendary chamion

Dude you don't have to participate at all.    You don't have to waste space saving champion  you're not going to use. You can completely ignore it.    I've gotten around a dozen legendary champions in the fusion system.    The only thing you need to do is fuse one epic champ in order to progress  in  missions. After that ignore it.

I think Slucan is talking about the fusion champions that are around all the time, such as Rhazin.  Their challenge is that they heaps of the champions needed for Rhazin (i.e. the champions that have the fusion icon below their portrait) and these are just taking up space, and at most it will just get 1 legendary.

@Slucan , the game isn't set up in a way so that the same champion can be used to fuse multiple legendaries.  The ones for Rhazin will only be used for Rhazin.  Every month there are fragment/fusion events, and if it's a fusion then new rare and epic champions are introduced for them.

As a result, you shouldn't keep hundreds of rare champions that can be used for Rhazin.  They won't be used anywhere else.  If you don't care about fusing the epics for Rhazin multiple times (i.e. for points in tournaments) then keep just a single one of each fusion rare and use the rest for food

Which suggestion?
