The combination of Charge Weapon and Smite Evil is a pretty standard hybrid build for people wanting a Paladin-type character., the Recharge spots are pretty much up to you so it you want to go for the group heal and attack, go for it. You'll definitely be doing the tank's job of generating Threat out the wazoo. That said, it's generally best to focus on three stats rather than to try and divide your attention, so you should probably consider focusing on either Agility
or Toughness. Personally I'd pick the former, since a lot of your boss damage is going to be coming out of Smite Evil and you
really don't want that to miss; Cleave's great for mobs but it's wasted against single targets so for bosses you're gonna be relying on Smite Evil (or swap out Cleave for something else).
If you go that route, you can make up some of the difference in Toughness with the reworked Veteran perk which makes it much easier for a Warrior to equip Heavy gear that makes them better at taking hits without taking a huge penalty to Initiative. If you find yourself having trouble with taking damage, Spiced Wine can help, because what's more responsible than drinking and brawling?
