I've got... eheh. A bit more than a couple.
Bestian Trueflight - level 20 Ranger/any (main)
Clocked over 1,000 characters on this character. Been everywhere, done almost everything.
Boudicea Hierophan - level 20 Warrior/Elementalist
Second character, but has barely seen the light of day since Factions.
I Eat Charr - level 20 Elementalist/Monk
Probably my second favourite to play.
Leaf Greydawn - level 20 Monk/Mesmer
Needs to go to Nightfall/EoTN and get the newer elites to realise his potential
Naya Casyric - level 20 Mesmer/Elementalist
Survivor character. Just hit L20, taking an extended break from grinding.
Vultorr Skaarj - level 20 Necromancer/Mesmer
Pretty much exclusively used for 55/SS farming back in the day. Almost never played.
Winter Stormcry - level 20 Assassin/Elementalist
Used for a mixture of farming and general PvE. Clearing dungeons as her at the moment.
Anubis Yythalla - level 20 Dervish/Elementalist
Raised primarily to wield a customised Destroyer Scythe, as it's the only destroyer weapon that looks worth its cost.
PvP Characters - all skills, items and heroes unlocked.
