Do I push through the main quest or complete a lot of sidequests in D4
I know it's most likely a beginner question but it's what I am I suppose.
For extra context, I generally have about 6-10 hours to spend to game per week and I find I do enjoy the main quest but after spending a couple days only doing that it feels like I'm missing out by ignoring some of the side quests.
I only have 1 charachter so far and it's lvl35 at around the start of ACT2.
Will I lose out on powerlevel if I just try to get through the main quest first for now and look into doing sidequests afterwards? Am I making my life harder if I do sidequests first?
Right now I think I would like to be able to participate in the seasonal with a new class to try out, since it is still an expensive game and I want to feel like I experience more than just one class.
I followed the rule of getting enough renown to get the region progress bonuses up to the third level for a total of 2 skill points and 1 potion capacity in each area. Otherwise as others have said, progressing to where you earn your mount really speeds even that up since you can traverse the map quicker.
