I've seen a few examples of DPS rotations here on the forum, including a video tutorial for Visual Studio.

However, i've no dea how to create a raid healing rotation as the Fight Class Editor only has the 'For friends (party)' option to set to True or False.

Is there a similar 'For friends (raid)' option?

 

Looking forward to write a healing fightclass for myself.

Also, expansions matter. 

There's a free shaman healing fightclass with source code attached here:

 

For Holy Pala there's something here:

 

@MateniaThank you so much for the heads up. Gonna start getting into C#.
