Guild Wars 2

not a knew idea but something you could add to keep the game fresh… or you could make it a little different special masters with quest that allow you to morph abilities/unlock

Tbh the morphs that are already in the game I tend to stay away from such as the Norn elites. Why? Because when transformed you are usually at a disadvantage as you lose access to your heal and utility skills (as well as being classed as holding a bundle I think so you lose any trait/rune bonus as well such has HP regens etc). If anet would remove this restriction then I would be all for it but until then I just see it as a waste of time sorry….
