Some skins cost less than 5€ (4), most skins cost between 5 and 15€ (10) and some skins cost more than 40€ (3). I will try to explain the reasoning for this with an open heart:


They are optional cosmetic items that don't affect gameplay:

• It does suck to really love a character and see that your favourite skin is out of your reach.
• However, out of any other item, skins cause the least pain to players who can't afford them.

They are 3D pieces that cost a lot of work hours to produce:

• If all skins were priced proportionally to the time they take to produce, they would all be around the 10-15$ range.
• That would leave a lot of players without the chance to own at least one or two skins for cheap.
• Mercury points gained with invitations, which don't cost real money, would never add up to any skin.
• In order to have some skins that sell for much less than that average, we need to price some of them above the average.
• Players who have the possibility to buy these skins subsidize the other skins that sell below production cost.
• Ginebra and Loaht's skins take twice as much work because they need two different models.
• It makes sense that these are the skins chosen to be priced higher than the others.

That argument for time spent is bonkers and here is why:
You can buy Witcher 3 Game of the Year with all DLC and Expansions for less money,and they spent years making those.
I understand that you need to make money and game did not that have a great start,but you should be looking how to attract more players not turn them away.
Make unlockable  things such as cards,weapons etc.  easier to obtain.Also.,find the way to implement cosmetic stuff akin to those in games like..TF2 ,dota 2 ,League of Legends..so called cosmetic hats ..for less money ^_^
I mean,even Riot games invests a lot time in creating those and still prices them not more than 25 euros for Ultimate skins...
Think about it,dont panic..game is good..just think of a way to attract people
