i hope that premium theme developers charge more and give the highest quality they can. i am willing to pay way more then 100 dollars - maybe up to 300 dollars - when i finaly get themes that i

do not have to beta test myself in the beginning and beta test everytime an update is released,
that work on every browser they say it works,
that works on every device when they call them responsive,
have perfect support within 24hrs/5days per week,
work perfect with multilingual plugins like WPML,
have best SEO practices and integrate with plugins like yoast,
have website speed always in mind,
do not have useless high amounts of .js, and so on!

what the wordpress theme developer pool is realy missing is that the best theme development companies should build an allience where you need to be super good wp theme developer, with multiple high quality themes on their belt, to get in. themeforrest is like a casino when you buy a theme from a "elite author" ... besides avada and 3 or 4 other themes i always had problems in some kind of way... and we bought about 75 to 100 themes the last 3 years for customer websites always from elite authors ... so everybody is an "elite author".. that does not mean anything, trust me... "elite authors" should realy be a small group of coder with higher prices and better quality.
