Earlier today, I was teaching a few of my friends who had never played the game before how to play. After a few matches of losing against medium bots they started to figure out last hitting and staying in range of creeps for XP and whatnot. I had been running hard support with Omniknight and Treant Protector to try to keep them alive and putting some pressure on them to last hit. One then asked me to play something more active to see if we could win one. Cue Axe. I have never snowballed harder than I did in that match. At one point I was 6-6 and we were losing a little bit, and then I finished my Linken's Sphere. (Already having a Force Staff, L2 Dagon, and Aghs) Bane couldn't lock me down anymore, so I was force staffing around with my Dagon and Culling Blade, just melting people. Threw on a Bloodstone in short order, then Heart once I realized how much gold I had piled up from scooting around the whole map (with my new Blink Dagger) and culling everything. Level 5 dagon on a 15 second cooldown, Culling Blade on 10 seconds, and a kill just about as often as both came up and I caught something. Ended up going 42-6 by the end, even spawn-camping Bane and Viper while the creeps finished the ancient. 989 gold per minute, more than I think I've ever gotten. On the other hand, medium bots.

EDIT: Second favorite part of that series of bot matches: I was checking out all of their inventories to see what they were buying, and I noticed my friend playing Ursa had both Tranquil and Phase boots. When I asked him about it, he just said, "Bears have four paws."
Can't argue with that.
