Barb seems very strong with the recent buffs, especially now with the re-added dmg to lamentation. Barb is also very mobile and easy to play.
Not saying crusader isn't but Barb appeals to me much more so I'm going for spin2win this season.
As others have said, it'll be hard to split between Barb and Crusader in season 19, I'll be starting as WW and transitioning into Crusader if they make it into the new speed meta. I think even with the cap added to the Fury shield they will still be better than Impale DH in most cases... only time will tell tho I guess.
