I don't think you are going to want to use the Round Robin feature for your standard attacks and debuffs.



I understand you don't want to send a big nuke on the initial attack, but I think you'd be better off setting up a few groups of keys for each class:



Button 3 = Main DPS spells/macro for all toons.

Button 4 = Main Debuffs spells/macro for all toons.

Button 5 = Main AoE spells/macro for all toons

etc. etc.

You can break the groups down even further to your liking/needs to get more specific actioins.

But the goal should be to keep them casting and not waiting on their turn to cast (via round robin).



Try to group all the spells so that when you press the 3 button, each toon casts the spell you want at the same time.
Then you'll only need to hit the button once.



Most of us have our heals set to other keys that aren't used by non-healing classes, this way the healer can aslo be free to do a little DPS.
Use a stop casting command (can't remember what it is in EQ1) to start your healing macro so you won't have to wait on a spell to finish if it's being cast.



Where round robin might be useful - If you have more than one healing class in your group, you could rotate out heals to reduce aggro gathered by one toon.

You will probably run into problems with round robin from fizzles and resists on the slow, then you would have to wait on the round robin to get back to the shaman to try again.



Hope this helps a little..I may have missed stuff..need more coffee.
