Are you using fight-classes that you have made or are you using from the forums? If you have a poor fightclass, it might not be the grinder profile that is bad, thats probably just the fight class. If i may ask, what class and what level? It might give some headaches in the beginning but i promise you, once you set it all up it runs like clockwork.
I mostly write my own profiles but i have used
to great success (when it comes to low-lvl profiles). Link the fight class you are using and we might figure out what the problem is, and perhaps a log. And when you get a bit more advanced you can write them yourself with 100s of different options when to use abilities so dont give up!
