Trumpets definitely needed. You don't need to rename yourself every few months, though. If you want to change your name that much, you should have to pay for it. 2 is plenty.

Now group name changing is different to me. I could see maybe 1 or 2 of these being handed out in some way just due to people/leaders leaving the game and server merges forcing groups to merge. I'd imagine it leaves a sour taste in certain people's mouths when they have to figure out which of the 2 or more groups is disbanding/leaving their group to form a bigger group just to be under the same name as your old rivals lol. You can buy group name changes, but making 1 person buy the whole thing doesn't seem fair unless it's their decision alone. Make a way to donate to a group name change fund lol.
