The scripts that are used (I am guessing) were based off of headshot scripts and that will make bots harder.

YaPB is alot harder tha podbot mm no doubt about that.
The old PodBot versions are harder than new versions.

Any body can shoot through corner walls, or most walls at that.

The skill level specified in the cfg should tell the bot to be noob or professional, but the codings could have also been altered in the new beta versions.

I'm not using the beta version, so most of the stuff I just said, are guesses.
