Well ... in previous PFH Swen told us that they didnt decided yet if level 5 will be part of Act 1 ... mind the wording "Act 1" not "Early Acess" ...
So there is quite safe to presume there will be some kind of (at least soft) level cap in final release ...
But he also said that if people keep asking, maybe one day they do that ...
Hard to say if he was just sarcastic, or if that was hint for some future update.
Personaly i would not expect level 5 sooner than with last implemented class (more likely next patch after that). But can be wrong ofc.
I hope they don't cap it once the game leaves EA... because if they do I can tell you right now there will be certain side quests I skip entirely and just simply go to Act II. Capping the Level (especially at 4) per act will cause players to stop exploring and simply move ahead, thus possibly never playing certain content (like I will probably skip out on helping Mayrena every single time if I am capped at lvl 4, because there is no reason for me the player to do that fight without the XP motivation as the reward for that quest is lackluster)and really I am sure Larian doesn't want to dump resources in to making content people don't simply because they go "Oh, I have hit lvl cap I may as well move on." If I am Larian (or at least part of the creative team) I would want to do everything to encourage people to explore side stories/quests and options rather than bulldoze through the main story skipping all the side stuff and there is quite alot of side stuff to do that you would miss just by playing where the main quest line(s) lead you and you will still easily hit level 4 before the end of Act 1... If I am correct you'd hit lvl 4 WAY before the end of act 1 as I don't think Grymforge is quite the end of Act 1 in its etirety.
