Yes, I'm just going by my own experience. 
I used LN for a while when Bitcoin fees were really high.  But, to be honest, I just got tired of using it later, since I didn’t notice any serious savings on transaction fees, simply because there weren’t too many payments themselves.  In my case, it was clearly not thousands of transactions per month.  Eventually I just got tired of it and stopped using LN. 
The majority of cryptocurrency users apparently do the same thing.

Why you get tired - is it more time/effort consuming?

So what's the consensus on LN usage fro crypto casinos? When the network is stable - LN is not necessary, right? so the majority of time...
