there is already an option to reset skill tree.. at right where you spend your 1st point. no trainer need.
Annoying how? This seems like a luxory problem more than anything, can people just be thankfull that we have a trainer at all? CheatHappens have no obligations to make anything, and certainly not make a trainer with as many features as this.
The thing is, that all these "suggestions" clearly annoy at least some of the developers here, and certain trainers have been abandoned because of this, or at least a contributing factor.
You might disagree with this stance, and I do HEAVILY disagree with the fact that trainers are abandoned because certain people are not satisfied, but it happens, and I just honestly want to avoid this with Payday 2, especially because I can see this game getting updated quite a bit.
Let's just enjoy this trainer for what it is, incredibly awesome, despite a few very minor things here and there.
