I cannot upvote this enough, and you're absolutely right with the jumping thing. I've lost count of the amount of times I've blinked into what I thought was going to be a group of 3 people waiting to eat my shotgun, but by the time I exit the blink they're just not there anymore and I'm left spinning in circles trying to find someone. It works. I've been running bladedancer ever since I unlocked it at level 15 on my very first character, so take it from me - it works. I really hope they don't f*** blink up. There's nothing wrong with it at all.
