Are stealth builds bad/mid?

New to the game and haven't tried a stealth build, haven't even seen anyone else playing one or talking about them either lol. It does feel like you give up a lot of potential team support or damage to go the stealth trees for Vet and Zealot.

I was thinking about trying stealth on my vet specifically but to my nooby little eyes the trade offs are either losing an ability that lets me melt hordes/elites or losing an ability where you just go "GRAAAHH FUCK YOU CHAOS!!! INDOMITABLE HUMAN SPIRIT!!" and beef up your whole team for...not that much utility? Obviously there might be (probably is) something I'm missing or reading over or whatever but what's the community census on this?
