Return of Reckoning

Got really tired of wow classic, and wanting to get into warhammer. I paint the miniatures and I play total war. I’m fond of Greenskins and dwarves. I’m split between Black orc and ironbreaker, maybe even slayer if I don’t want to dps. If anyone can sell me on the class or tell me about them. How they do end game and if there needed

Borc = best single target dps tank with 2h, Sword and board are very tough, assist utility to debuff armor, buff toughness. Require stance dance (Difficulty = med)

IB = best duo utility tank on order side, paired with slayer is very effective. Buff pretty much everything you can think of for you and your oathfriend. Hard to master because you have to manage both oathfriend and guard (Difficulty = hard)
