However: even moreso than in past years, you won't want to scout with it. A team might get a 60-70pt OPR without ever firing a ball. If you also don't shoot a ball, you probably want to find a shooter or a low-goal specializer. If you already have a fantastic shooter, you may not want to pick a team that earned their OPR with a shooter. In past years you could maybe get away with picking the top 3 in OPR for an alliance, but with such different functionalities and roles, you'll want to make sure that everyone is compatible.
Also, keep in mind that you can't always compare across events with OPR - an event where everyone tends to play offense and keep to themselves will elevate all their robots OPRs, compared to an event with heavier defense.
Another thought about the penalties: It would be interesting to not only remove the penalties from scores (as has been done), but to actually subtract them from the team that caused them when putting inputs into an OPR-solver. This would help find teams that are racking up a lot of penalties, since their OPRs would go much lower.
tl,dr: OPR will be great for entertainment purposes to do comparisons across robots who do different tasks, but poor for scouting.

At Inland Empire, we had a robot that only had a drive train playing only defense--no shooter or pick up mechanism with a middling OPR (and ended up an alliance captain), and another that was having quite an offensive day (our 3rd alliance member) with a low OPR despite showing high in our scouting data. The OPR this year seems to be greatly influenced by the schedule and win-loss record. And with 13 matches apiece, this was the best possible statistical mix of any event.
