What do you expect? He's an elf. Time just does that sometimes.
On a more serious note, I prefer the time skips. Gives the world scale. A lot of stories feel like they are just weekend trips. Like, you've been fighting the demons for hundreds of years, and some rando demolishes them in an afternoon.
I'm grateful for the chapters.. but man this group could really use a proper PR/QC.. At least I got to catch up to however much is on here since I started reading it back when there were only three chapters.
