I want more realistic stuff, knighty plate armors, assassin outfits, realistic weapons, etc.
I don't mind fantasized version as long as there are realistic ones as well.
In GW1 a Warrior could wear some great armors like Primeval, 15k Plate, Knight's... and use realistic battle axes such as Victo's.
Assassins had all kind of shady outfits, Eles had some good non-gay wizard robes too.
I had an hard time trying to make my thief look like a Thief, and I'm still struggling to have my Warrior and Guardian look like a realistic knight.
I really like spiked maces and there is none. I like realistic longsword, there is none.
Maybe with time we'll get all this, I just don't get why in GW1 you looked like this:
And in GW2 you look like this:
That is one of my gripes with dyes and plate armor. Bright and saturated colors don't always look great on everything, and the huge spikes certainly don't help. Otherwise you look like you're wearing a cosplayer outfit rather than actual armor.
Aion's art direction was great, though there were still a few silly weapon skins. On a side note, I think Lineage II did pretty well though for B to A grade gear.
