They can.
Here my opinion about PRX map pool
Bind: PRX homeground
Split & Fracture : Above average for playoff team standard, but will be defeated by King of The Map (e.g.: EG's Fracture)
Pearl: Amazing! They struggle in defender but better than Split and Fracture
Lotus: Pearl Reverse card, strong in defender
Ascent & Haven: Average playoff teams, better than BLG and FUT. Would lose to Loud, EG, EDG, DRX, Fnatic
