Maintenance that added ninja skills was on Wednesday 7/23. I turned on Mini Effects around Friday of same week and haven't turned it off, even after the maintenance on next Wednesday that was supposed to fix some crashing issues, because right after that people kept creating threads about random crashes after the patch, and that were merged into thread talking about ninja skills causing crashes (not to the cutscene-related ones or any other).
On the other hand, if Nexon learned to create some proper changelog, a lot less people would be upset too.
You should consider trying it and see if you still crash. Those people that created their threads may have crashed for a different reason. It could have been their computer, internet, etc, and they were just looking for something to place the blame on outside of the scope of it being an issue on their end.
