It's been a long time since I've played Blood Bowl, and I forgot one of the reasons I stopped playing. That reason would be the Whiners. I guess there's no avoiding them because I've run into one or two here. Guys who whine when their dice are no good. Or whine when yours are too good. I had one guy bash on me the entire game for making one die blocks. I tried to impress upon him that with a blocker, a one die block has only a 1 in 6 chance of failing. I'd bet 5 in 6 odds any day. I had another guy disconnect because he was losing. Fortunately I got him to reload and simply concede the game.
Granted, I do my share of complaining. Usually this happens after my twelfth double pushback, or rerolling double skulls and getting them right back. However, I find it funny and don't whine about it.
Just remember, it's only a game that in the end rests on a randomizer. Relax and play for fun.
