IMO enemies already give too much XP... no point adding more ontop of that. I would be more for cutting their rewards down in favor of raising Quest XP. But that's me.
And no, summoners should not give more XP just cause they summon. It's their attack. That's like saying sword wielders should give more XP since swords. Mages should give more XP since magic! And rangers should give more XP since bow damage! In the end, it all balances out, or you get an upward spiral out of control.
Yeah, I'm sure Larian is smart enough to see why summoning/respawning XP is an actual issue and spawn change on reload isn't, and the difference between actively seeking out ways to "game" the system (which are obtusive and take a long time) and those that are passive, and as a result can be triggered without realising, and if actively engaged are far easier and rewarding to "game"...
Again; Apples and oranges.
EDIT: And I would go further... aside from being a waste of time and a LOT of work (I know, trust me) it's also actively making the game WORSE. Who wants to persue that? I know I would say 'screw that' and work on something else instead...
