I'm going to be constructive about this sale Riot.
The champions are fine - many will always complain about the champions that you pick because they already have them.
Skins, however, are different. Sure, people will complain regardless, but if you recently had a skin for the same champion on sale not too long ago, you are not going to get as much money, right? So you not only dissapoint your customers (bad for sales loyalty!), but you don't make as much money either (why buy another skin of this champ?).
I believe this sale was scheduled for this date before you even decided on the player choice sale (esp. with Dec-Jan mass holiday nightmares). What you didn't do was go back over your schedule more than 1 (or 2?) sales in advance, if that.
So let me tell you why I will not be purchasing any skins this sale with RP.
I just purchased Firefighter Trist and Red Baron Corki during the legacy sale - these skins on sale are not nearly as good as the ones I just got in my opinion.
Teemo had a different basic skin on sale during the promotion also. So for those that just got that, you are missing out on their money Riot. It is also not a very good one compared to the others, so I will be patient and wait for a different one.
