How about a Traditional Summoner as in a Summoner who can summon almost all existing "Summons" and where every Summon is unique in some way...
just saying....

I don't mind if they're small, I just want them to be more meaningful than they are now...

Also, lore is just an excuse since it's only mentioned in the Summoner questline
and if they're constantly draining us even when not active then why wouldn't we be able to use them all at the same time.
