Summoner as it is now is a good class. A total overhaul would be a mistake in my opinion, the class only needs minor tweaking and trying to make it align with the idea of a summoner thematically at the expense of how the class plays isn't a good idea. I don't really understand the desire to make it "more" of a summoner anyway myself. The class is already heavily reliant on summoning, you just don't have to constantly summon while playing it. I'm fine with SE adding a class that has you micromanaging your pet, but Summoner should also stay the way it is now.
