Hey,something been bugging me:
im lvl 13,and since lvl 11,i gain xp/ip in some practice games witg bots,and in the most i get -100 penalty!
why is that?
and last night i got xp from a 3x3 with bots while i was testing a build from my recently bought Kat!
could anyone clear my mind why this happen?

There are a few more rules than that:
1. The game has to be even (1v1, 2v2, 3v3, etc)
2. After lvl 10, you only get xp for 4 practice games per day - each game resets on their own timer I think
3. Each game must last longer than 11-12 minutes, I forget which
