In reply to needforname.

I meant that low quality of themes are not only on Themeforest. I don't care much about Themeforest, I don't like it at all and I don't use it and will not buy anything from there.

Actually I use Make https://wordpress.org/themes/make/ on more sites, I like how its flexible and designed. Still prefer more lightweight themes, but did not find some at the same level.
I hope some new quality theme shops will arrive soon.
