Hon, this question has been answered ad nauseam by more than one person in this very thread. Myself included. Seriously. It's starting to feel like we're shouting into the void at this point. For details, I highly recommend going back to read some of those entries. However, in summary...
HAVING ALTS HAS NOTHING TO DO WITH EXPLOITS, RAIDING, INVENTORY, OR ANY OTHER SO CALLED 'CHEAT' FOR MOST PEOPLE.
It really doesn't.
I have two characters. Both characters have 9 retainers (I am not afraid to pay for more inventory to keep myself organized). I could not care LESS about two more free retainers on alts. I could care less about raiding multiple times a week. I don't care about the blasted mogstation either. I simply buy what I want for BOTH characters if I like it enough to spend the money twice. I don't even care specifically about MSQ now that I can new game+.
My entire reason for having two characters is because I had an old, retired, main I decided to reinvent into a new character with a new name and a new backstory. Sonja is a completely different person from K'rina, and I enjoy the difference in their personalities as I play through the game. That's it. That's the reason. And I see no reason why I should have to spend a fortune in fantasia and name changes because I want to play something other than my kitty.
By that same token, K'rina IS my main character. She's wealthier and further along with things than Sonja is. Being able to craft things on K'rina to send to Sonja without having to beg an FC mate for help or commandeer the FC chest for a while, is not an unreasonable request, and honestly I don't get why you and a lot of other people are so against it.
Unless you think we're all cheaters and exploiters who should have our accounts banned because we have the gall to pay for more character slots, use them, and then ask that it be a little less of a pain to do so? Because that's the impression I'm getting from all this outrage.
