skins and champ sales, why only 6 per week?

i have been playing this game for many years. when i first started playing maokai was the new champ.

to my point, back then there was half as many skins (and maybe even champions) but yet we still only put 6 skins and champs on sale a week just like we did that many years ago

i know personally if skin sales happened i would spend more money on this game. i think its time they look over that model. esp since some of these skins have been going on sale for years now

does anyone else agree that there should be more skin/champ sales per week due to there being so many out know then compared to a few years ago, or am i alone on this matter?
