Part of what gave rangers such a huge advantage out in pvm world was the fact that they can res and tame their mounts out in the field. As this is certainly a perk that rangers themselves should retain alone given their specification, I still think it would level the playing field a bit if there were similar options for other pvm classes.
For instance, maybe a bard could use a skill on mountable creatures to “tame” them. Or a mage could resurrect and animate dead on a mount in order to retrive their mount for the duration of their hunt.
Just dreaming big. 😛
