Is your game style heavy on the roll-play and lower on the combat and skill checks? 5-10 rolls seems low to me, even for shorter games.
How many rounds do your fights last? I'm playing a cleric - I get maybe one roll a round, and not even that if I am casting spells that have a save (like ye standard Sacred Flame), rather than a spell attack roll.
My dice make me irrationally happy.
Ain't nothing wrong with that.
