As a healer absolutely np as long as I was also allowed to cast protect at the start as to avoid immediate suspicionWith DPS I'm sure I could cook up some ghastly macro that would work sufficiently well to ensure I didn't get kicked from most runs, don't think I could get away with it on a tank tho =(
The no carry thing kind of makes it tricky though, technically every dungeon/trial would be a carry due to the slacking I'd be doing by mashing that one button the whole time =(
Makes me kind of gutted that I have such horrible internet speeds at the moment, that'd be a pretty fun thing to do.
To take that idea even further, I wonder how far down the line a 'twitch plays FFXIV' would get, lock in a particular job and only allow commands for movement and combat abilities, script it so it'll only ever queue for the highest level dungeon available to it. I'm legitimately intrigued as to how far it'd get assuming SE wouldn't take offence and ban the account of course.
Maybe it's a recent mmo thing I guess? Simply sitting or standing on the wrong place in an FFXI or Everquest dungeon could wipe out multiple groups and in some cases even render the dungeon a no go zone for a few minutes whilst the resulting train cleared. I remember dungeons in WoW being more akin to FFXIV's late beta and early release with CC rather than aoe being the usual choice. BnS dungeons were pretty similar though with the trash being little more than chaff that got in the way between bosses =(
