Just curious but why move away from Octopus? I'm using that still -- HKN and Keyclone haven't really had feature updates in a while as far as I know (I also have a Keyclone license). I thought about switching from a /focus system to a FTL system, but then I really couldn't think of a good reason why -- with Octopus PIP hotkeys and Jamba focus support I have F1-F5 bound to swapping mains and it does so in under 10ms including auto switching the current window. The only two reasons I could think of moving to FTL are (1) if you need to use focus for CC, (2) if you need to use focus in PVP for multi-target/hidden target blasting. imo at this point there is absolutely no CC required in any heroic instances, can't speak for #2 that much since I don't really arena but not really sure its necessary.

IS is the most powerful and has more transparent FTL setup, but it does cost $36/year, whereas the others are free or 1-time fee.
