Blink is already taken by Warcraft, is it not? Might want to think of a new name. Like... Squadelah!
Note: Original Dungeons & Dragons releases in the 1980s (and probably in the earlier Blackmoor books) had "Blink Dogs" that teleported as part of hunting-pack behavior.
WoW has ripped-off every concept in game from some previous game. MoM has this in abundance as well. In games like these, every idea you have and can have has been thought of, spec'd out, or implemented somewhere else. Its not a big deal unless it is a specific copyright or trademark infringement.
Thinking of all of that makes me all misty-eyed for the days when we played Empire of the Petal Throne tabletop ... that was a serious RP game. Going off topic, sorry, but EotPT was awesome.
