Blizz points

So you get one point every two hours you stay in game, ok. The problem is that i play, for example...1 hour and 50 minutes, and it disconnects...i have to start those 2 hours again, which in my opinion is not fair.
For example, i disconnect after 1 hour and 50 minutes, get back online, play for 1 hour 30 minutes and really need to change my char...so in total i have played, what..3 hours and 20 minutes and i still got 0 points. Something should be changed, i do not really know how it works, save the time or what.
yeah...that is what has been bugging me, just wanted to bring it out.

 

sometimes 4hours,

dont know why sometimes it took 4 hours to get 1 points

 

always 2 for 1 bp for me
