You're free to disagree, but some of your points are off.
You're arguing from the stand point that enemies aren't already going to target your squishier party members in tactician mode, which Larian has already said they will. Invisibility or no it's going to happen. If you're not playing tactician mode, worrying about such things is premature.
Any class can deal damage, even the "healer." This notion that there is some ironclad separation like this is an MMO is utterly false. Yes, a character can build to specialize in healing, but even then they have access to many means of causing damage, as well they should.
On the side, if you're going Dark Urge you already know you're going to be alone, party members may not be concern for long anyway.
But back on the topic of invisibility not being strong-
Invisibility provides:
- An advantage on your attack coming out of invisibility.
-Freedom to move out of danger, giving you distance and an opportunity to get to high ground or just disengage from a fight entirely.
-Damage mitigation seeing as the majority of foes won't be able to do anything with you being invisible.
-The ability to avoid fights entirely.
-An easier time stealing and interacting with well guarded objects
-Various generic advantages in RP and unconventional interactions
These are all things all classes can benefit from in excess.
I don't think you understand...what is a Sorcerer going to do with invisibility? Nothing...it's a ranged caster that strikes from distance and does not gain any benefit from stealth and doesn't even have the damage dealing capabilities to reliably activate stealth. It's a total waste. You can try to force it but it will only cause problems. Especially on tactician where you want enemies to die as fast as possible you want to put that on a character that a) reliably activates it and b) benefits from invisibility for more than running away. It's a total waste on anything but a rogue. Sorcerer is more of a AOE, battlefield control, support class.
