You simply dont waste much time as a dev on items that only the top10 of each datacenter can aquire. You ask for emotes, unique glamor, unique adrenaline effects for a pretty small pvp community... As for player icons, how should other people tell by looking at it, whats it supposed to mean, it is more confusing for 99% of all other players.
I agree though, earrings suck. In WoW top arena player had a pvp mount that was running like 10% faster as the others, something like this would be easier/faster as to model or create systems entirely new.
