How about a relic weapon mount?

The Amaro was a really lame as a reward for leveling EVERYTHING

That's, like, your opinion, man. I thought the amaro mount was a very good reward considering that the expansions before you got only titles to show for it.

On op's topic a mount would be cool but I wouldn't mind it just being a title. Could be one for each set (one for ARR, one for HW, etc) then maybe if you get them all you get the cool mount.
