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 suspect you're downvoted for stating false information. Even now it seems your supposed evidence is literally from suspicious (to say the least) source.
People following your advice expose themselves and their children to harm if follow your advice. Complaining about a downvote seems rather silly in that context.
