Treant Protector in 3k

I was curious, if Treant Protector is good at 3K or if I've just had some bad luck in my games. Seems like he doesn't really do anything. Sure, we won the laning phase and walked away with some kills. But, after that all I have is a root and slow.

When I was playing the other day, I thought I would have had way more impact if I had been at dazzle vengeful spirit, or a shadow shaman. Seemed like the most team fights, we had I blink in, stun slow, heal someone, and then I'm pretty useless after that. Where as the other heroes I can come in stun, shackle, snake. like there's so much other heroes can do. Sure tree can heal, your teammates, but damage wise and utility. I feel like he's not doing anything.

I feel like my team isn't utilizing the vision. You get with him through his shard. And built grieves in the game, I would say, and yeah, just didn't feel good. I feel like dazzle. I feel like we were just straight up one if I would have had dazzle or a shaman in this game.
