Not really...because it only activates when you kill an enemy. Early game or against bottom tier enemies it will work for any class but later on and against tougher opponents it would be a waste to have that on anything but a damage dealer. But it goes even beyond that, you need it on a character that actually benefits from invisibility for more than running away...you really don't want your front line damage dealers to become invisible because then all enemies start focusing on your squishier party memebers. To make proper use of it that cloak has to go to a rogue...there's no other class for it really...high single target damage and hits a lot harder from stealth. The rogue is designed to strike and hide on repeat. At an actual D&D table nobody but the rogue should take that item because it would harm the overall effectiveness of the party.
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.
