IF they do level cap us per act and act 1 is lvl capped at level 4 you are going to have a few types of players
Yup ...
And if they dont (no matter what level it will be really)
There will be different few types of players:
- Those who will follow the main quest line ... they end up with level 6 (lets say) at the end of Act 1 with some gear.
- Those who will follow the main quest line and occasinaly do some related side quest ... they end up with level 6-7 with decent gear.
- Those wtho will completionist everything ... and they can end up easily with level 8 or 9 with best gear possible.
Now how would you like to make an encounter for all of them?
