It doesn't really have a bloat problem. Some controller players think there is one, but a lot don't know about the W-hotbar.

Its generally only specific jobs that have too many buttons, and more often than not, they are bloated with buttons that should be merged (smn bahamut being separate whereas phoenix was not seperated from an attack) or useless clutter people don't realise they should delete off their hotbars (benefic 1)
