SEMI RELATED TANGENT TO THE OP, sorry in advance
First off, yes, wiz/enc is gimicky as hell, absolutely true. Its also obsurdly difficult to actually get good at, and even being good at it doesn't make little mistakes any less painful.
When I first read this I was like ok you convinced me I'm on your side. Then I thought about it after the fact and I have a huge issue with this:
You're arguing that wiz/enc doesn't compare to the efficiency of healer/melee with kills per hour, using this as a justification to make mobs snarable. If you're soloing, you have exactly the same amount of kills per hour on a wiz as you do with wiz/enc. So your best case scenario for this as a duo would be boxing two wizards and yo-yo kiting with aggro, with a snared mob? I just don't understand how making mobs not summon and making them snarable is going to drastically increase your kills per hour, short of just making it exponentially easier to do what wiz/enc already lets you do. I mean I'm not fundamentally opposed to this concept I'm just trying to understand what it is you're after here.
Also the bad stun argument is a completely irrelevant argument to the wiz/enc thing, which makes me think you kinda just toyed with the duo and didn't really try getting good with it (again, I've got nothing against this either, just trying to bring clarity to the argument). That zone is literally the most difficult thing I found doable with wiz/enc before the dps threshold becomes too high for the whole thing to work, and a mob or two are beyond that threshold.
