I played a fighter in a friends campaign, and damn if I wasn't the character the party feared most for over all combat capabilities. This was a party containing a reg Summoner, two other full casters (Cleric and Sorcerer), and a crazy optimized Magus.
My fighter could deal as much damage one handed with his falcata in a full-attack (Haste and Fleet Charge from mythic) as the Summoner and his 8 attacks with haste, and could spike damage harder than our blaster Sorc. In addition to damage, he also handed out debuffs like a madman if the enemy wasn't mindless, or immune to fear. Shaken and sickened, and then possibly panicked/frightened if the enemy somehow was still alive.
Want access to movement shenanigans? UMD, or all the magic items that give you an extra movement speed. Past 7th level as a fighter with Armor training 2, your heavy armor doesn't impede movement. At all.
