I'm not sure on the Summoner question. If it applies there too, it should be resolved as well. I also agree that, given SE's history re: balance adjustments, it might be best to have an option blocking auto-attack from initiating combat (but otherwise remaining the same), as opposed to eliminating it for certain jobs and scaling ability usage accordingly. In theory the latter is perfectly possible, and would be an easy way of resolving the problem, but it's quite possible that SE wouldn't adjust skill damage properly.
