Me? I like there being a little weight to my decisions and I like when they aren't made wholly inconsequential by arbitrarily getting to go back on them whenever - even if those consequences are on me, or I'm not wholly able to foresee them.
I'll not throw a fit if re-assignment for Grand Companies is implemented, I guess.. but frankly I'm glad it's not there and my vote will always be against the option. Especially given all the warnings. Now, if the change were possible at some significant penalty or other..
Oh and just on a point of interest - My primary Discipline is Lancer, I'm with the Twin Adder.
Not that some means of dealing with the other Grand Companies wouldn't be nice.. Jennestia's point above, for instance. Still, they've said they're thinking about that idea anyhow, haven't they?
