i wouldn't want gore but i can see a lot of potetntial in more empathized way of handeling armed conflict (like in the comics, for an instance when the pirate ponys are clearly shown to wield cutlasses and a fight is depicted with sayed weapons. even magical violence is shown by twilicht roasting the pirates with some kind of shock spell.), The fight against tirek was somewhat of an appetizer for what potential the show could have with a bit more adventure and no fear to show a sword or a spear clashing together from time to time. ^^
i would still be AGAINST a depiction of death or graphic wounds but sme armed conflict couldn't hurt the shows appeal to manny. (considdering how popular the royal guard and the nightwatch are amongst bronys).
also showing a swordfight in a kidsshow isn't that uncommon and could be done if you considder that they even showed an alcoholic baverage in the show =D
