This was one of the things I have liked the most about Pathfinder, just because it is not a nat 20 I still have a chance to crit.

Take the short flaw.

I run multiple games without, but the one game I am in the dm (this is his first time dm’img) uses a screen religiously. Although he tends to forget there is info on the screen for him. I think he only uses it as a barrier between us and him.

I do not use one. I do all my rolls out in the open, and mostly use over sized dice so my group can see them.

As far as rules, the group keeps me on my toes for them. So I just keep my notes in front of me.

Well that clears things up.
