An opensource project will always be as strong as the somme of investement of each single menber. Luxcore will perform better as time goes on it is clear but every single user can make the project own and help it to shine.Luxcore seem to be powerful yet simple enough to use, but there is still a lot missing and I think I'll give myself a break from it until there is at least "light cache part II" available. I bet 2.1 or 2.2 will be amazing.

Why a skillfull Coder will continue to worry about a code people wann't try or use
You're already a skillfull artist and each time you work with luxcore without give up make you better and help the project to improve. I know it can be really frustrating somtimes (for example i'm actually working on complexe stuff without the possibility to use Ctrl +Z in object mode. It'snt Luxcore code problem but Blender Bugg).
Take your time. you've done a lot of test in so little time with a totally new renderer plus the fact that you come from Vray or corona World .......
I hope you will continue to be part of the story even in it's sttruggling period and be more proud of it when it become the diamond you're waiting for.
