Maybe I'm missing something, but the spirit breaker nerf seems pretty weak, no? He'll be easier to lock down, but still has huge damage and will only farm a little slower than he used to...
No witch doctor nerf? Seriously?
It's in there
Oh you mean the bs stun nerf next to the ult buff?
On brackets where people actually remember that Witch Doctor has an Ultimate that can easily be disrupted and people save stuns for that, he's not actually that strong. Of course, on lower brackets, that doesn't happen, everyone is surprised when Witch Doctor activates his ult and Glimmer Cape.
It's not the ult, it's the shard. Even as a 5 he becomes a nuisance in late game that does incredible damage. Even when you try to stop him he just activates his shard and you can't do anything.
I mean winrates in higher brackets float around 51% for him, so yeah, while he may feel problematic for you, he isn't really too strong, just a little above average :)
