This involves a menu, or even an on/off switch, where you select equipment from your inventory to be displayed in.
The game displays you wearing whatever you selected to be shown in. This would allow players to display their "Town Gear" in action, while giving mages and other support type jobs a much needed breather. Client side you would still blink/swap gear etc. but to other characters you wouldn't.
Blinking personally hasn't been an issue, but I think it would go a long way to preserving old achievements as well as promoting having your own sense of style.
