I suppose unsurprising given my "stop nerfing things!" comment, I'm very much for leaving teleport as it is: I find it much too useful
I have a similar stance, but it isn't even based on how "useful" it is. I honestly don't even find it that powerful.
It's just that it's a very FUN ability to use and abuse, and I fear any significant nerf (after they already lowered its damage quite a bit in the last build) could turn it in something DULL.
