Help me pick a DPS!

If you don't like following a script, that excludes all three melee (and double excludes drg because of blood of the dragon). You already shot down SMN and BLM. MCH has a pretty involved opener like SMN, but a little less micromanging involved...but it can be hectic making everything flow for wildfires and keeping track of the off-gcd skills. Pretty much the only thing I think would work for you based on your post is BRD. The opener is fairly simple, and after that you just follow a priority system rather than a set rotation.

After that, if you don't mind positionals I think you would probably enjoy monk. It has a rotation, but it's a lot less involved than ninja or dragoon once you adjust to the positionals. You don't have to keep track of huton or mudras like ninja or worry about blood of the dragon. Also, missing a positional is a lot less unforgiving on monk.
