IDEAS FOR RYZOM

Not sure if you know this or not, the thread seemed to get into other areas fast.
Macro:
line 1: Target Teammate #x
line 2: select shortcut bar 07
line 3 : run shortcut 14
line 4 : Select Shortcut Bar 06

If starting off in action bar 6 will target the teammate, run the heal action at location 14 of action Bar 7,
and return you to action bar 6 where you started.

I realize you want more where the macro could be put on any action bar and return you to that action bar -- and i would like that too but what you want is doable.

As to all the other points, the macro system is very good as is and does a rather good job of avoiding becoming an ingame botting system.

It's just a suggestion: if Devs will decide to not develop it I bet no one will do seppuku. ;)
At the same time, someone other than me seems found it useful and extended the concept.
And others warned about possible side effects too.
This is the best use of a forum, IMHO: try to reach the best, or at least to suggest it.
