Heyyo,
Did you crank up the difficulty on the bot? plus, turn on old turning style, so they turn around instantly, and shoot at you instantly, that'll add some challenge.
Well, you might wanna try a harder bot. Wbot, IMO is the hardest bot to fight cause it's soo damn good. E[POD]bot also has a special difficulty booster that when turned on makes it twice as hard as normal PODbots. (so the difficulty setting goes as high as 190!, most bot's 100... well, tha's difficulty settings put in lamen terms... but it should still be plenty hard.)
So try those 2 bots out man, they should give ya a hard time.
But remember for E[POD]bot, it's good at sniping, but IMO IvPbot has the best sniping code, cause it's not instant, but acts like a l33t would snipe, make sure he lands the shot 1st shot.
