Isn't this game supposed to have four acts and a level 10 cap? I feel like we'd reach that cap within the 2nd or 3rd act...
Not sure about count of Acts ...
But as i mention at least once per week around here, 10lvl cap was canceled about a half year ago. :-/ We still dont know wich will be new cap, but it certainly will be more than 10.
Also i dont think that leveling slower is something that will solve anything. O_o
Maybe we are suppose to reach level 5 with first act, its simply not implemented yet ... all that is suppose to come will come in its time. :-/
There is no reason to tune game for early acess, when you will tune it back afterwards for full release.
