Anyone remember the "enigma" runeword from Diablo 2, that would allow anyone with that piece of armor on to teleport like a sorceress?
What if Zeni introduced a 7-piece dropped or crafted armor set that would give a player access to one particular skill (or entire skill line) from a different class when equipped?
If EVERYONE could bolt escape, no one would have cause to complain. Same thing with talons, banner, etc., etc.,... and sorc healers could actually compete with templar healers. Sorc/templar DPS could actually compete with DK/NB dps.
This would actually, for the first time ever, allow you to "play any role with any class", which zeni has claimed since lauch but failed to actually deliver.
