My first character was healing in a raid team. On that character I levelled all jobs to level cap, one of them being PLD. I enjoyed tanking so much that I decided I wanted to main tank in raids, but didnt want to leave the team, those being friends of mine. So I made a second character and level capped it, decked it out, formed another raid team, and main tanked all content in that raid team while healing in the first raid team on my first character.

Regardless of whether characters were created with the advantages of being able to swap class instantly and having cross class abilities, there will be valid reasons why people want an alt. Subscribers should not be disadvantaged in any way by having alts. We pay to play, we have the ability to create new characters, mailing items to our own characters should be available. Square Enix needs to fix it regardless of personal opinions as to why we shouldnt need them. They are just opinions and the need for mailing to alts is a fact.
