I am playing in a campaign where it seems I will likely always be a level behind the party. For some story, we play every Sunday for 5 hours, but I have work through it so I only get around 3 hours in.
We used to play so that it was a milestone format and I would level up with the party. We have now moved to an XP format and only presence gets you the xp (I think to avoid some people missing sessions and coming back still strong).
My problem is not with the format, but trying to work being a consistent level or so behind. So my question mainly is, what class/subclass works best when you will always be a level behind the party and trying to still stay relevant.
