I'm starting in a campaign at level 3 that I know will go to 20 (we've completed 2 campaigns in this group already so i have faith we'll get there). It looks like I'm going to be one of the 2 main "tanks" of the group and I was thinking of going with a half-orc barbarian/fighter. My initial thoughts were to go Barb 3 levels then go all fighter. This way I get rage, reckless attacks and bear totem (to make me tanky) from the barb, then I get the extra attacks, asi, and action surges from fighter. I was also planning on going with a two weapon approach, partly cuz I like it, and party cuz I'm planning on taking the champion fighter so more attacks = more chances to crit. I see a lot of posts that seems to take more barbarian, but the brutal critical doesn't seem to outweigh just having more chances to crit. Am I missing something that people like taking more levels of barbarian than fighter? Also any other thoughts on the build would be appreciated.
