Its really not just people using blink to kill you that makes it a frustrating ablilty to fight against. I can't tell you how many times I'm about to kill somebody and they blink behind cover. If they had used any other movement option in the game I would have been able to finish them off. I don't know what would be a good way to fix blink. I don't like the idea of increasing its cool down or anything similar to that. And i also think decreasing its distance by any way would completely ruin it. Maybe making it a more horizantel movement might fix it. Blink is the strongest form of movement in the game, and i dont think anybody could question that. Blink just doesn't fit with the other movements in the game. Eventhough you can counter it, its not like everybody with Blink equipped has a big sign over them saying "Hey, I'm using blink". And if you always have to be watching out for it, then you can't really say it's balanced.
