Yeesh, yeah, I can see why premium comics would be where most of the tips are going... understandably so, of course. I don't have nearly enough subs to even activate tipping for my own series yet, but well... I set up a patreon for a reason. XD ; Considering releasing pages a week early there.
Either way though I hope tipping doesn't sink completely, since I hope to make at least some use of it. And ads are low enough as it is...
