I'm really hoping to do a build with an elf Phalanx Soldier using an Elven Branched Spear and getting up to 11 to get Pin Down, but going straight fighter bores the snot out of me. I thought about just taking enough fighter levels to be able to one-hand the spear with a tower shield then using Daring Champion from then on, but sadly Cavalier and Fighter levels don't stack for the former's bonus feats (which is stupid, IMHO). Any suggestions? I don't particularly want to go Swashbuckler instead since I really dig Banner and Tactician for this build.
