OK, first off the team has stated in the past on multiple occasions that stuff like IG stigma surrounding animation doesn't factor into class balance. Once we acknowledge that, then purely from a mechanical standpoint trading conju summons for necro summons isn't a bad deal. Some would even argue that's an improvement (at least for the time being - you never know when it comes to summons).
That being said, the core issue here is what has been my biggest pet peeve with specialist wizards from the get go - it's not me who doesn't want people to have fun, it's how these paths have been designed. The crux of the argument is that players would love to have their cake and eat it too when the very identity of the specialist wizard paths is built around the fact that they cannot.
You're literally shooting the messenger here.
And once again I reiterate that the thread has been derailed - there are underlying issues regarding both wizard and sorcerer classes that aren't being addressed by specialist wizard feedback here.
Frankly (and I say that fully appreciating all the work that went into it) I'd love nothing more than to see the whole module of specialist wizards just axed and vanilla wizard and sorcerer be made actually good instead.
Edits to fix grammar.
