Indeed. Pity the culture is so... unfriendly? Rematches are basically non-existent - even in bullet! It's bizarre, and I have to assume it's going to limit the site's growth.
I just got hooked on lichess after not playing Chess since I was a kid, it's a lot of fun, I also spend a fair bit of time in analysis...
Lichess matches people by rating, so on average, if I blunder my way into a large deficit, my opponent may just as well blunder me out of it.
Not a chance. People at lower ratings screw up what should be wins all the time. Your opponent may be hoping for a stalemate or to run out the clock or waiting for you to blunder.
