they didn't make changes they brought on their sub, overall prx can beat sentinels prx can beat loud. prx are a very skilled team, they have the best player itw when it comes to player pools, they have insane mechanical skill.
they'd be considered slightly overperforming, but they're always one of the tournament favorites, due to the experience and mechanical skill of their core
I would say if they can hit anything like what they did last year its considered overperforming because Jinggg is such a huge loss that still isn't talked about enough.
