The problem is that while combat focused PC have armour, high initiative, multiple attack per round, and don't fail their roll. You're like acting at the end of the round, once when other PC do it 3 times, fail your attack and as soon as you get hit you're unconscious. The cool part of putting the big combat at the end of the session is that you can take a nap, and have the GM waking you up at 5 combat is over, let's give the XP and the first train homes leaves in 30 minutes
