Is full auto mode supposed to mean just auto attack? Or full auto as in what? I'm not really sure what that option does
So, I have no idea what a Guardian does but this is what you can do to find out, it's what I did to be able to answer your question.
Find the Guardian.iss file in the Class Routine. Search for the word "full". The only hit I got was for "FullAutoMode". Then search further in the script and in the CombatRoutine function there is an "IF" statemtn that checks if "FullAutoMode" is enabled.
In that "IF" it basically casts all of the CA spells that a Guardian would use.
So to answer your question "FullAutoMode" will cast the following CA's:
LayWaste
Obliterate
AA_ExecutionersWrath
AA_AccelerationStrike
A few different Taunts, AE and single I guess
A few attacks
Shield_Attack
ThermalShocker
Now you can dig into the script further by searching the "case" CA's that will be listed in the "Combat_Init". This is where the "case" spell numbers are located. Find the "case" and then the "number" and then open the the Spell List file associated with the Guardian and find out what spell is being cast for each "case".
It is really simple. Just open the Class file and the Spell file and figure out what is happening.
It is very easy to change the script also, don't let it scare you. Make your own.
Just post what you made so you can help others.
