Pitfalls? Heck, I've had nothing but a smooth ride since we switched to 5E. I might warn you that early levels (1&2 in particular) can be swingy as all hell (a la Rocket Tag), but you probably gathered that just by looking at low-level monster stat blocks.
Bugbear, I've got my eye on you.
Are you using feats? Also the human variant?
