I have 8 million blade shards.. according to forums we will be able to "do something" with spare ones, they said not to delete them. Best way is to just bag farm. I'm bag farming for tomes to lvl my engineer as I am apparently still burned out on lvling alts from years of WoW. Actually years of WoW has completely coloured how I play GW2, only just decided to do a craft after swearing off them. Have farmed luck up to 172% though.
I like the different races and how non human some of them are.
