I generally really like the armor design of ESO - but some pieces, particularly certain monster sets, look... Well they don't agree with my aesthetic preferences.
Sadly; things such as monster sets and the invariably Celestial-looking Twice-Fanged Snake set (or Necropotence, or any of the other grinded things) are pretty much the only viable options end-game, so; seeing as Jewelry Crafting isn't a thing for now I have an idea.
Once a Character has learend all chapters of a crafting motif, they get a costume for Light/Medium/heavy of that particular set. Like I love the Dro-m'Athra style, and I'd like to look like a crazy, electric, daedra-khajiit without having to dumb my character's effectiveness.
Hell; you could even sell the option for this in the crown store.
And now that I got your attention with a money-grabbing chance; can we adress some of the issues that make players quit/whine-and-drag-down-the-community? I know you're working on PVP lag, and I know (due to the universal human trait: stubborness) you won't rollback Morrowind's sustain changes; but could you make sustain at least a little easier? Alot of people are really, really hating how Heavy-Attack spamming has become, not an optional build, but the optimal build for alot of DPS, and even if you have a spamble like Force Pulse of Flame Whip you're still bound to weave in heavy attacks sooner or later, because of how hard sustain is.
And so my second suggestion is; let the community somehow vote/compile a list of top 10-20 issues to fix, and get cracking on those (I realize big issues like "lag" aren't just "fixed", but stuff like "this boss in that dungeon always messes up; this ability is underpowered; this set needs to change; these abilities should be cheaper for better sustain, etc).
I think it is central to ESO's well-being to critique the developers when they change the game (or fail to change something).
But the negativity can be exhausting, so I vow to post 50/50 negativity and appreciation.
