Honor level bugged

Hello, Almost every game i get a honor, have clear record with no bans for abusive language, play like 20+ games per week and am still at honor 2 - 2nd lvl. My question is, is this system bugged, because with the previous honor system I got level 5 in like 2 months or so, and now I level up once per year (i've leveled up once). And most of the games i finish with 2-3 honors, I do honor every game, and the key drop rates are DISGUSTING, like I get 1-2 per week and play 20+ games...
