I haven't got to do combat in 13 real world session hours.
So long story short we added a party member's brother to the session and ever since everything dies before I get my turn in rotation even things that should be super tanky. They both play minmax monk style builds with some barbarian and dish out multiple attacks every turn that move the enemies around the battle mat. Last night's session I was there 6 hours and didn't get to make a single combat roll out of 4 different combat scenarios. How should I talk to my DM about adjusting enemy health so I feel involved without making later encounters impossible.
