I forget if you play 4e [MENTION=18701]Oryan77[/MENTION] but this could have something to do with your current issue...the players learning complacency (and being slapstick) because they aren't challenged enough.
Naw, I run a 3.5 game using Pathfinder classes converted to 3.5 (my own homebrew). Luckily, not a single player in our group is a fan of 4e. So they don't have any expectations or gripes for how I use the rules.
They actually have made comments about how difficult my encounters are. Not in a bad way. It was just an observation they had in regards to how I run encounters. Apparently, even when I use low CR creatures, the encounter is still tough. I like to think that I'm a good tactician and also good at multitasking with many NPCs at once. I can finish offf 10+ NPC initiatives faster than two players can finish up their actions. So I think they are being challenged more than enough. I actually threw lots of low CR creatures at them at once last session just so they can flex their muscles and feel tough by stomping all over them. I noticed they needed a pick-me-up like that.
