Nope this is unacceptable. I could wait and just buy each of those skins when they're 50% off and save so much more. At least on the bright side these aren't replacing the weekly 50% off sales, if they did that, they'd have a....Riot...on their hands.
To make the bundles appealing, the Yi/Teemo bundle would have to be 747RP and the Brand/Singed bundle would have to be 974RP/975RP.
I mean, at least when you buy the Champion Double Bundle when they come out, you get the skins for half off (Champion 975RP + 2 skins (975RP) = 1950 bundle). Now those are decent, even though I never buy them.
Also Mad Scientist Singed is currently on the unofficial Skins Blacklist and could be going on sale soon for 50% off, while the Super Teemo and Yi skins both were on sale in the past couple of months.
