My main is a Charr (basically I'm recreating my orc) but my Asuran may well take over in the main department.. I keep thinking this is what gnomes were supposed to be in WoW but never really got enough development on. Very interesting race.
As to the deleting, well nothing else was ever useful that was tied to an event so it's not surprising. I have one character whose bags are full of them, he's my closet. I try and follow the forums, and see some stuff on tumblr, it does add to the game as far as people's lore discoveries and actual information. Learned what NPC's died that way etc..
I go through phases with the world boss train, it's useful, it's fun and sometimes it's utterly tedious but that's what music is for
