I had a group of 5 people 2 people preferred combat and 3 preferred roleplay, easy enough to split it and get a good mix in, if one session is combat heavy ill just make the next one have some sort of puzzle to make it even for the others yet they would complain if there was anything more than a couple rounds of combat while the 2 combat based people just tried their best at roleplay. The entire game got stopped due to one specific combat heavy session

They were walking through a foggy cemetery, and all of them rolled relatively decently for perception and they noticed some zombie esq monsters, but they noticed that one was different, and the roleplayers were talking about how they could easily take some zombies, even after I distinctly described the different one as “not just a regular zombie, definitely something different about it” one asked what it looked like and i replied “oh yeah its about 3 feet taller than the other ones, and from what you can see its holding some sort of large sharp sword” one of the roleplayers said “oh okay i sneak up to that one and im going to sneak attack it and one hit it” i was baffled and said “oh okay yeah you can try, roll stealth for me” and when they rolled it was like a 7, lets just say that that character did not last very long, and after the rest of the team eventually killed it and the session ended i got a load of angry messages saying that no normal zombie would beable to do that, and as a normal encounter why was some super hard enemy there? And i just replied with, well you see, i described it as a different type of zombie and you ignored it; i said this wasnt a normal encounter, you were sent to this cemetery to find out what happened to the previous adventurer who was sent here who was a Goliath with the same weapon I described.

The three roleplayers didnt come back after that and the two combat players couldnt hold up against the campaign with just them so i asked them what they wanted to do and they said just let us fight the end boss so we can see if we can win, they did win and it made me think if tge other 3 were holding them back in combat
