Anyone else feel like key frag rates are just too abyssmal even after its been a while ya got 1?

I don't play and breath LoL excessively but i feel like after getting 3 chests from S ranks (support Cho'gath, support Sejuani, Aram Morganna), granted the support cho'gath was a lost but still I've gotten at least 5 wins in regular game modes between now and that S rank with support cho'gath, i really feel like Riot needs to buff the key frag rates so they are at least guaranteed once every 3 wins and only have it decay to about 5 or more after you got 6+ key frags. I can understand its 'free loot' but having a good deal of uncertainty like maybe a lack of knowing how close you are to a key frag is silly, especially when one is sitting on 4 hex tech chests...

Anyone else agree with me? Maybe they should 'increase' key frag drop rates based on how many chests one has too. Because if it takes me more then 15 wins to get 3 key frags then i feel really bummed out...

I do know its usually set to be around 12 or so key frags a month but they could at least allow the pacing before hand be enough for a 'casual' player of LoL to be able to earn it, not one who has to grind a holic for it.
