Low priority is too harsh

I understand low priority reasons, but it is very harsh. I have disconnects in 2-3 games out of 50, sometimes long enough so that i cant return to that game (1-2 in 100) due to my connection. But there is no better connection where i live. Why is this 1 dc is punished with increasing low priority timer? (it was ranked, but 1 game? And it was first leave in like 50 games 99%) It really should have some kind of redeeming mechanism for people who dont leave for n amount of games (20-30 may be). And less harsh definetly. (I would be fine with 5 min low priority, but 20 for that one leave is crazy)
