While that makes sense, it now opens up the situation of a caster now has to role against a healer (aka: me) on caster gear because I want it for a secondary job, whereas it might be an upgrade for their main. If the itemization in the new one is the same as Rab, I will be healing it and rolling on exactly zero pieces of healer gear. They've now turned me into competition with casters (and tanks because I have PLD) when I wasn't before.
Thats the downside to this. I can take upgrades for a main because I want them for a secondary job. That's not something I want to do. An awful lot of years of ingrained MMO etiquette says that's bad, and I'd feel bad if it happened. But they've removed the means we have to avoid it except someone asking "please don't roll on the paints, they're an upgrade", others having to remember that.
