No kidding! I just looked at your rolls. Other than the first roll, which still succeeded because the goblins rolled low, they've been 17, 17, 19, 20, and the non-d20 haven't been too shabby either
The dice gods are feeling generous but as the dice gods give, so can they take away.
No doubt a string of 1's is coming my way, lets hope that we don't all roll crappy at the same time. Most of the party wipes I have seen have been as a result of all the players being unable to roll more than a 3 on a 20 sided dice.
