I understand your frustrations and wishes/hopes
but the fact still is that making a skin takes a very long time, and making a skin for laptops are twice the time of a normal skin
as said, its still early in the game cycles and lots can still come out, but i agree that more and more are moving away from making laptop skin simply because they either don't feel it's worth it if they don't use it themself or that maybe changed from laptop to desktop themself (or got a external screen)
The community is year after year given something for free in most cases "lets use the SAS24 laptop skin as example" it's optimized for 1366x768 85% which is the normal resolution for most smaller laptops and if you for some reason can't use it because of the zoom, then i'm sorry to say that the problem lies at your feet.
Not liking a skin for whatever reason is perfectly fine, we all have preferences and needs of how we would love a skin to look. but it does limit the choices of usable skins.
Learning XML to make a custom skin is no small achivement, but being a pro at it is not really needed as "almost" everything you'll ever need is premade for you from SI side and we just move things around to fit the creators need
and thats how it often start and i dare to say that "almost" every skin out there is made because the skins that were avaiable didnt have / live up to what the creator were looking for to enjoy and play the game like he want to, so that he/she wants to share his work is only a bonus for the whole community and not something he's forced to by any means,
And yes.. There is years where few skins are missing, that can as you say yourself be down to ppl "retire" from skining.. but some are also stopping because the demands and or negativity towards what has been made gets too much.
Anyway: at the end of the day, we as a community have to remember that Skin is made by unpaid volunteers and given to the community to enjoy, so if ppl don't like something, pick another skin or make the changes yourself (and yes it's not easy)
I hope there will be something that fits your needs and that you enjoy using. Happy gaming!
