Why would you even make your main a STF character in the first place is what I'm wondering. I guess a foolproof mechanism could be added, i.e a STF character can't be your main/your main can't be STF.
I didn't bother to grind to have a fully enjoyable main char, meaning my main is a stf char.
I started to play a long time ago, i quit crpg for some times, i came back and saw that my char was pretty fucked with gen wipe, recalc, bugs, and patch. What i did? delete this shit and create a new one, I started back and didn't want to grind for life to have a semi decent char, so I skiped the fun, but now I have fun!
