If armor kits were toggle-able to ALL your armor indefinitely after purchase, that would work much better.
Why would a lvl 1 buy an armor kit that he'll replace 5 minutes later? He won't.
I also don't like the idea of having to purchase an armor kit remover.. that seems kind of silly.
If it's a requirement, say because of the way the database works, at least make it cost 1 TP!
Anyway, I really want to start purchasing armor kits, but I'm not gonna' if they don't change things. D;
