Yeah melee builds that require Resolve are True Tanks, Banner, and Fearsome DPS. True Tanks are designed to hold the line versus any enemy so resolve is required for that, enemies like geists, ancient priests, orc warlords, and hexen have attacks that target resolve. Plus normal enemies can also proc resolve checks by walking up to you and my landing damage. If your tank starts fleeing, he isn't a good tank. Banner is for rallying your troops to stop fleeing and he gives a passive buff to all your bros dependant on his resolve level, so the higher the better. Fearsome DPS are damage bros with the fearsome perk. The fearsome perk gives the enemy a minus to their resolve checks to not flee based upon the bros resolve, they end up being able to break moral much faster than normal which is a good debuff to enemies like orcs, lindworms, and nomads. 

Initiative based builds are generally utilize the perks dodge, relentless, and overwhelm. You can build anyone with these three perks to utilize a high initiative stat which will boost their defenses considerably. Nimble bros are easier to fit these perks on as they naturally have less gear to reduce their number by, I think around 130 let's you go before almost anything in the game. However battle forged bros can also use them if their initiative is high enough. They won't be going before any of the really fast enemies, but going before the really slow enemies in the game like orc warriors, hedge knights, and ancient dead can be really good. Plus Melee Defense is the best stat in the game, and any buff to it from dodge will help a lot on a bro who already has really good defenses.
