Defender and Guardian should be Tank titles

The titles for Tanks don't do justice to what a Tank does for their team. The role of a tank is simple, soak up damage for your carries so they can do damage while you defend. The support titles are all right except for Defender and Guardian. Those both sound like Tank titles to me. A tank defends and guards their teams from damage. Grunt is more of a soldier, bruiser should go over to fighter, I don't know what a Bulward is, might be a typo for Bulwark. If so, then it fits the tank role. Enforcer is all right, I guess. Brute sounds more like a fighter to me but whatever. The bottom line is, Guardian and Defender should be a tank's title instead of just a support's.
I think more along the lines of a tank, someone who will body block attacks for allies.
(and also
who are often built tanky but don't really have a protective vibe to them, although they can peel, it doesn't define their identity in the same way).
not getting them, probably wronger.
are defensive mages who can support, and
are offensive or defensive mages who can support (probably emphasizing their defensive side), and
are offensive mages who can support anyway.
