After reviewing the posts on public forums and this one over the past 2 years, WotC has failed to respond to the community's repeated requests for faster play (speed matches, weighted time-outs, 10s mulligan, etc.) and common sense match making filters (on-format deck sizes, block/ban lists for non-tournament play, etc.).

Folks do not have the time or inclination to wade through 20 minutes of snap-conceding to jank off-format decks (playing 100+ cards in a 75 card format) or known jerks who "rope for fun" just to, maybe, get in one quality best-of-three match in 60+ minutes of IRL play-time.

I've ceased to care about my win/loss record.

I'm putting Arena (mostly) back on the shelf until some reasonable match-making filters and genuine disincentives for unsportsmanlike conduct are available.
