Porting is great and everything, but I had, what I think to be a pretty cool idea to tweek the portal ability.
Spell: Star Portal (not the best name lol)
Ability: Save one spot anywhere outside of a dungeon & alliance owned areas to be able to port you or any group members to that area.
It would come in handy in raid situations, for example, before the raid begins you could save a spot right outside the entrance. If repairs are needed you could port everyone outside the raid to use a repair vendor (I know there's repair bots obviously, but not every group has them). Def. a big time saver sometimes.
It would come in handy for doing quests, for example the shado-pain dailies have that annoying manual flight to the quest islands. You could save a spot to one of those islands etc.
While pondering this I also had the idea of having blizzard implement a system where if someone took any of your ports they would automatically have to give you a certain amount of gold. Not that I'm a greedy player or anything and I always give free ports, but it would just add some extra revenue.
It's nothing crazy, just an idea...
