What would you think of a "hide allies" and/or "hide all players option" put into ESO that people could use whenever they pleased?
I ask this because it is virtually impossible for me and some others to even enter a city or other populated areas during prime-time due to the latency (sometimes it's the only time we get to play). Everything becomes frozen and can't be interacted with. While it wont decrease all lag, it may certainly rid some of it.
A few years ago I played Aion, and one of the few great things i remember is when it was getting a bit overpopulated, or when you were in a massive group or alliance and you could feel the latency kicking up a gear, you could simply Shift+F12, and poof - every ally in site would immediately vanish (showing only healthbars) and your game would increase tenfold as it doesn't have to load/keep track of every texture on each piece of armour or clothing in you vicinity.
This could be a great optional setting for anyone to use in my opinion
