The Old Exorcist
I tip when someone gets my character right; it's not uncommon for some users to get it wrong. I also tip posts I read where I'm /not/ involved, but the combatant either takes his loss gracefully, or wins respectfully.
I tip this way as well. To be honest, I really get bugged by the tendency people have in the Dome to consider rolls an indicator of a character's battle performance or something. This isn't a quality check, like in D&D. I mean, let's just use Eunica fighting Nyrk, for example: There is just no way in hell the fight would be easy, for her to win.
If a fight is is going to be a curbstomp, your character better be good enough to actually curbstomp her through their character--not because of some stupid dice roll. =_=
