If you have the shards and are not hell bent on gearing up an alt on the same account, then why not?
I haven't heard that SOE is adding nifty new shard equipment (doesn't mean it wont happen in the future) so what else are you going to use the shards on?
The TSO legendary shard gloves ARE nice with the haste. Depending on raid/group set up you prob wont be at the haste cap so the gloves are a nice bonus.
I'm sitting at 200+ shards now wondering wtf I'm going to do with them. I could really give a crap about my necro alt on the account.
So I say, if you have the shards, spend them!
As far as VP set, the 2 set bonus reinforcement is something you prob want to keep.
Just my 2 cents and def. not gospel!
