Perfectly fine. One keystroke-one action. We used to do round robin using manual castsequences but isboxer has really simplified it for us.

The way you describe it you will lose your base FTL assisting for 1 -> =. You should make your round robin do a keymap action instead and point to the 1 - 4 keymaps in the FTL assist section. Round robin and assisting. /bam
