Depends on how it is handled.

If it does not destroy the guild focus and what not I have no problem with it, if it make it where it is easier to instawarp into things with a dungeon finder then to do things with a linkshell then I am completely against it.

If they find a way to do it without hurting the linkshells I see no harm in it... but atm I see that as something hard to do atm. They add Dungeon finder most people will use that instead in the games current state.
