Hope they didn't ban all bots on WC3.
Some of them were quite useful, such as bots used for auto hosting (maps such as The Black Road had almost all of their users use the host bots. The bots also recorded all gameplay to look for cheaters and a mod could directly intervene via the bot whenever needed).
Diablo 2 on the other hand, screw the bots.
I was into WC3 for quite a while only 6 months ago, but I grew bored.
I tried playing D2 again, but running 640x480 on a 2048x1152 monitor is depressing. I also lost my expansion key so I could pimp out a druid.
I do miss Diablo 2 though. I sunk a incredible amount of time into that game. My favourite was 3 hammerdins, all with different auras, running around and raping bosses. The cow level was also awesome (I was depressed when I saw the WoW loading message 'there is no secret cow level').
