I'm not a Templar main, but I think it would make more sense to shift it to 1/2 of the morphs instead of both. Keeps both parties happy to some degree, it has some unique potential... Even if Templar tanks aren't optimal choices, it never stopped people before, it's not gonna stop them with subclassing.
I want to try the charge taunt in lep seclusa 2nd boss so I can keep front bar ice staff (currently using shield charge to get to her before being chained). The taunt part should absolutely be a morph option though, with ZERO dps utility.
