We really need an indicator to tell the if a target is taunted and then if it is taunted by you or not plus how long until the taunt falls off. The debuff list in this game is insanely long, so using that to see your taunt duration is pretty difficult especially in fights where you are tanking 2+ enemies. For example when OTing vAS2 or vSS HM Navi statues it is very hard to keep track of which Mini/Statue needs a taunt refresh without relying on addons. Even then addons like Untaunted just give you timer bars with a target name but if all the statues have the same name its impossible to differentiate. All you know is "one of the statues is losing taunt soon".
In most other games that use the better system of threat typically floating health bars over enemies change color based on the threat you have or don't have on them. Something like this but for taunt would be incredibly helpful. Currently it is impossible to attach floating icons to enemies using addons so this is not even a option. You can only attach floating icons to group members and that's it. By floating icons I mean icons that will follow that character around in the game space with them.
Either this or just re-work the threat/taunt system in this game. Its actually crazy that you can be doing 100% of the damage to an enemy and yet it runs off to someone in your group that is like 30m away who hasn't even looked at it yet.
