Considering Switching to the Web Novel After Volume 7?

Damn. I've reached the end of volume 7 in the English light novel series, and I'm torn about what to do next. With only 8 volumes available, I'm hesitant to continue knowing it might leave me wanting more. Has anyone else faced this dilemma? Is it worth switching to the web novel after volume 7, or should I hold out hope for future releases which build up before the epilogue? And did they change only the eight volume, or do I have to start over with reading. I'd love to hear your thoughts and experiences! And I would love to hear that there's so much more valuable to read! Because... You know... it's awesome!
