Titan Weapons is something that I was asking for, specific to tankers, years ago when the game was live.
Not specifically the giant weapons but a power set that is more representative of "active tanking". Why is the tanker the most dangerous one in the room? Because he or she will take on 3 or 4 of the enemy in one blow! Taunt becomes a tool for pulling stragglers off of team members rather than a core ability. Sure Titan Weapons is a bit slow in the lower levels but the Momentum mechanic along with a mindful attack string helps with that.
