Seeing as you are leaving an Alt in Seeds I wouldn't consider that leaving per se, and as a long-term member we all know you aren't a guild hopper (though you
are an MMO hopper

). I really wouldn't worry about it, you simply have a foot in each door which there is no rule against. If somebody wanted to take their Main out of the guild for Raiding purposes and leave their Alts behind (that has happened as I recall) in Seeds noone would take issue; removing your Main to go play with your friend is no different and in fact I'd say it's more understandable.
Surely as a casual guild, the fact that people want to leave their Alts behind is the sincerest form of gratitude and compliment.
Now get the hell off of our forum.
