They still have to make the goblins stronger, unless we want to make the game child's play (increasing the number of enemies is not the solution that will work for this game).
Start at higher level was just ONE suggestion that I gave.
After a miss, giving +5 hidden bonus to hit, for you and enemies on next round is the best solution. It would make missing 4 times in a row mathematically impossible, and if you have 50% chance to hit, you will never miss 3 times in a row.
