I personally have access to the beta and can say many things need and should be fleshed out. They probably will as it's a beta but as it stands Jason is sometimes a little bit too overpowered.
1. He can teleport anywhere - With a cooldown
2. He can use 'sense' which will morph him along a specific path you decide to go and can reappear almost instantly - Again with a cooldown
I understand the cooldowns are in place to not make it OP, however, it still kinda is OP that he can teleport any and everywhere at any given time minus the cooldown. At the same time, it is very easy to 'survive' the match via multiple ways.
1. You could repair the phone box and call the police whereas it starts a timer and once the timer reaches 0 you can run to any exit with police and escape the camp.
2. You could repair the car after finding the necessary components (Gas, Battery, Keys) and drive away. Note you getting in the car is not a cutscene you legitimately need to drive away and Jason can stop you.
3. With a little bonus but not a win, there are radios on the map you could find and if successfully used it will call Tommy Jarvis. Which a random survivor, if they die, will respawn as Tommy with a one shot shotgun that deals massive damage.
