Dual Blade Builds

I know that but you're ignoring what tornado spin does for training in general. Useful at MP3, C-2, WRs, SBs, gallos, himes, and others. I know you won't be able to hime that early on. It has pretty good damage for a skill that rushes 8 mobs and works with MI. That said, once you have a mob rushed with FS and TS you can US or BS the hell out of it. This kind of thing works with low levels of all skills except TS though, since each one still hits a good chunk of monsters.
