Just got them too, and am impressed as well. Safe to say its one of the best bots hands down, and a definate goal to work towards with my own bot.
The nade handling is still screwed up - I was on cs_office for a while, and kept getting naded by my own teammates.
I'm guessing that in the nav file somewhere, there are "hints" or markers where a nade would be a good idea (they always seem to do it around corners), which is a good thing, but they never take into account teammates in the area when they decide to do this - so theres been quite a few times where I'd be leading a pack, walk around the corner, then see a friendly nade tossed my way because it seems the bot already forgot I was there. >
Or, I'd see one bot after another come up to the same corner, stop and nade it, then go on, 2 or 3 one right after the other! 9_9 After so many nades, its safe to say its clear, but they were too "automatic" about it.
