This is actually an easy one for me. I build fighters the most easily because they most suit my play style. I’m not usually one for impressive displays of magic or the spirit of nature. Give me a hacky thing and things to hack at and I’m happy.
This may or may not influence the way I DM.
NB: Be aware of your leanings when you DM! Playing to your strengths and also branching out into your weaknesses is a good thing to be able to do.
Apparently I like A-names. I’m not sure why.
