People need to stop saying that we should be grateful towards the skins team.
In the end they're doing their job, and nobody deserves praise for doing what they should. It's like how people think they deserve a prize for NOT flaming people in their games.
If someone don't like a skin that is released they don't have to like it. Don't tell someone "At least you're getting a skin" because that just tells the skin team that no matter what crap they make, people will just accept it, which is just pure bullshit.
The skins team hasn't been impressive this year in a lot of peoples eyes. (Champins with tonnes of skins getting more, skins team not responding often/constant radio silence, skins themes being less varied etc etc.) So I think it's pretty natural that people are to be generally more on-edge with each skin release. It also tells the skins team that if people aren't happy, they shouldn't get lazy.
People are permitted to their opinions, whether they're sensical or not. Whilst I'm not one to say it's a good thing to go and say those opinions, I'm someone who believes strongly in people being allowed their own thoughts.
In the end, don't spout "Be grateful" when people really don't have much to be grateful for. Besides a legendary or two, the skins team has not gone above and beyond this year.
