Hell yes. Imagine, half a dozen massive war brontos, loaded down with cannons, catapault turrets, ballista turrets, and twenty guys all armed to the teeth. Rexes stomping everywhere. In the middle of the pack of brontos lumbering towards your base, is a single bronto with a platform bronto with a ring of wardrums, and painted maniacs pounding on them. Now, it would be terrifying if each wardrum player added +5% to a max of 25% buff to damage and defense on tribe dinos within a caertain radius.
Think the wardrum guys would be the first to go? It would add an interesting aspect to the game, for sure.
