I think it is great that the cows are going to implement this, however there are still a lot of questions about how it will be implemented and used. It warrants a review of the original thread where the reasons for having this skill were given and debated, and I am too lazy to do that.
Take a step by step approach, and implement it in stages to gauge its usefulness/abuse.
For example, release it for use on realm maps first, but not allow it for Titan hunting at this time.
Then if using it for Titan hunting is really really needed, then weigh the options at that time.
It is not necessary to implement the Teleport skill in one big bang, do it incrementally in quickies, it whets the appetite, builds anticipation and prolongs the pleasure.
