So , another good thing I love having on WoW was the Deadly Boss Mod. It basically tells you what you need to be doing in the battle and gives procs when a boss is about to do something you need to pay attention too. I think ESO could use something like this.
There's something like that for Trials. Notifier I think it's called. Unfortunately nobody's done anything like this for dungeons since Sun-Tzu's old mod. As a tank who often teaches PUG's dungeons, it'd be nice to have a tool that at least reminds me which dungeon version mechanics I might be mistakenly quoting, LOL!!!
