Kyn this might help in explaining what I think the OP is wanting you to look at.
if(spawn is TooDangLong)
spawn -= TheTooDangLong part;
else
GM.Explain("It is balanced for reason" + GMsReason);
if(mobcount is TooDangLow)
mobcount += ALotOfMobs;
else
GM.Explain("The mob count is where we want it because" + GMsMobCountReason);
Sorry I am at work and need a humorous sideline to distract me from the reality that is my job.
