I got into the alpha earlier this year and redownloaded it after the wipe and big update a couple week ago. Finally managed to get the maps downloaded and so I've been playing bot matches today. Pretty fun, pretty fast. I like the maps have different objectives to shoot for, I like that last hitting isnt a thing, and there is no in-match shop. It's all very streamlined to make for quicker matchups. My bot matches so far have been about 10 minutes long, and a few player vs player replays Ive looked at they seem to be about double that.
I've leveled my profile up to unlock daily quests, but those can only be completed in co-op or versus. I believe co-op is humans vs bots and versus is humans vs humans. So I guess I'll try those out but I'm not sure how the lag will be. The bot matches I've played had a nice little warning flashing that I have lag (duh) but its worked quite well. Cant say I really noticed any lag. But I dont know how much of practice bot matches is run on my local machine. Guess I'll find out.
