I disagree, having a small number of mounted troops has been proven very effective on our raids. The Undead were the ones to usually fill this role though. It's a bad idea having everyone mounted, but a select group that can ride mounts for certain raid spots would be cash yo. I know orc roleplaying is usually steeped in rigid tradition, but as the game changes, sometimes you have to adapt with new tactics or become redundant. It's not really that big of an issue for me and I would support the use of combat mounted orcs albeit in small number. They would make great pets to train and let loose on ommies too.
Also no bolas and no heat of battle? what kind of trammie shard is this :/
