The issue your argument has is your not stating why it is bad game design. I know you think that being yanked from your position is bad game design, but feelings and anecdotal evidence doesn't actually equate to bad design. You would actually need to provide solid evidence that the skill is causing fundamental issues in PvE content. And based on your arguments, you would actually have to prove that clears are harder to obtain because healers are severely reducing group DPS through the abusive use of Rescue. Good luck with that.
The other issue is the complete and utter inability to even listen to those in favor of Rescue, and their reasoning behind it. They have actually stated valid reasons not based on feelings or anecdotal evidence to give strength to their arguments. Whether you want to believe it or not, Rescue has saved a lot of players from eating dirt. It has been used in prog strats. It does require skill to use it effectively. These are all facts. I know it sucks to get punched in the face with the truth, but it is what it is.
Getting butt hurt when a healer yanks you just isn't enough to justify removing the skill. If you can provide actual feed of how Rescue negatively impacts the game, I am all ears.
