Round-Robin

I got 5 Shamans. I tried to find out how Round-Robin works. So I setup /Cast [target=tank] Healing Wave macros and bound it to ALT-5 for all of my shamans. I expected that one after the other will try casting healing wave but not all of them at the same time. But actually nothing happens, no ones casts Healing Wave. What did I miss?

thanks

You need to press it 5 times for starters. Each consecutive keypress will send to the next box in the round. As for it not going through potentially... I have no problems but I might recall others saying alt/ctrl combos not passing 100% of the time? Dont quote me on it. My RRs are all single keys (fear bombs, etc)

One of my RR's is a CTRL-F and I have had no problems. If you are experiencing problems I would double or triple check your settings (both that you bound that key in WoW properly and you put the proper key in KC's RR).
