One of the biggest draw for me in terms of the first Guild Wars games was how even the prestigious items in the game were still in line with the medieval aesthetic. Rare weapons did not glow, they were just well ornamented and appeared well maintained. Rare armor was detailed and appeared crafted with immense skill. Anything glowy was few and far between, with only I think one weapon set and a pair of gloves.
GW2 started off fairly similar, with muted but interesting armour design, and any glow or effects on armour or weaponry were fairly tame and in line with what NPCs were wearing (example: CoF armor which includes some flame effects which have been previously built up to by Flame Legion shamans also possessing similar effects.) It was generally sensible, and spoke more of a lore friendly magical 'infusion' through Flame magics or ghost magics and again, these were prestigious skins and were few and far between. Dyes were generally toned down also, with some brighter dyes which made sense for ornamental cloth pieces on armor/light armored characters where brightly coloured cloth made sense.
However, over the years, we have had far too many flashy prestige symbols added. The once rare fractal capacitor backpieces turned into huge obnoxious wings, infusions allow players to turn their charactes in glowing balls of light with snowflakes falling all around, you can't take two steps in DR before bumping into a human female in hotshorts with cat ears and angel wings. GW2 now looks like every other MMO on the market.
GW2 is an MMORPG, and at launch, the RPG part was comparatively pronounced, with the muted aesthetic, somewhat customised personal story, and the personality system. Now, I can't enter any major cities or explore areas at any medium-traffic time without being pulled from my immersion and hence my enjoyment of the game within half an hour.
I play the game to explore the world, to suspend my disbelief, to care about the lore and the story and take it at least somewhat seriously for the duration of my playtime. During the past few years, that has become outright impossible, unless I play very late at night when other plays are scarce (which I do enjoy, however I would like to not be so restricted?)
Now, do I think this should be removed? No! Of course not! The people who make their characters this way obviously enjoy it to some extent, and it would be cruel to both takeaway what was once given and to do it to please another part of the playerbase. Instead, I would like an option to customise one's expereince, perhaps in gardes of severity, with grade 1 hiding only backpacks, grade 2 hiding infusions and special effects on armor and weaponry, grade 3 hiding neon hair colours and particularly vibrant dyes, grade 4 hiding mount skins , and so on and so on, allowing a player to choose an experience that suits their tastes. If a person finds flashy armor and infusions and weapons annoying and unapealling they won't be awed by them anyway, and those who will will not choose to turn them off, so players who use them as prestige symbols will not be affected by such an option.
I don't know how possible this would be, but consiering how the aesthetics of the game used to be a major draw and now GW2 looks like 99% of MMOs on the market, and I think it would be a smart choice on Anets part to bring back that part of the games individuality.
