I am guessing that when the Coliseum (in Uldah) is open, we will have PvP matches between Companies. Perhaps some of the rewards for winning your match will be seals or gear from the opposing Company?

Just an idea, anyway.

As for the OP...No, I do not think you should be able to switch Company Allegiance unless you are stripped, flogged, humiliated and branded a traitor. Then you receive fewer Seals from your new Company because your allegiance is suspect.

Sorry, but I am "hardcore" when it comes to oaths, vows and promises...even in a video game. ;>)

Also, imho it is a sad commentary on modern life that so many people expect everything despite whatever personal choices they make and if their choices lead to undesirable consequences or impede them from gaining something, they want an "easy out" and a "do-over".

Sorry for a little preaching but I am kinda getting tired of the "..I want everything despite what choices I make" attitudes around here (and in RL)...

"I want to wear all gear"
"I want to join each company"
"I want all Class Abilities"
"I want to be a Lancer/Paladin"
"I want to solo to cap in 1 week"
"I want, I want, I want...I, Me Mine".

I guess I should just play the game and ignore these forums but I (like all of you) want it to be a better game and have my own ideas (good or bad) as to how to improve things, so I don't mean to be rude or insult anyone's opinions. I just ask for a little more humilty and understanding that FFXIV (and Life) is not all about me (or you).
