What are the current meta's in the game with XGtE out now?

There's a methodology that picks up rogue/barbarian as means to avoid damage. You play a dex-focused character so you can be SAD, then tack on damage resistance, then pickup uncanny dodge to further reduce said damage. Usually it goes Barb 5/rogue X for extra attack and more rages/day, but there are barb 3 or even barb 2 variations.

Personally, I think its kind of a pointless build. If you want to be unkillable or have infinite HP, I always feel like going straight barbarian or going with an armor of agathys-based build is just always better.

The synergy between Reckless Attack and Sneak Attack means you can always get your advantage/sneak attack off every round.

The synergy between Danger Sense and Evasion means you are better at dex saving throws than either the rogue or the barbarian.

The synergy between Rage and Uncanny Dodge means you are incredibly tough to kill, dividing the damage from a single attack by 4.

There are other synergies between the two classes. Rage + Expertise for superior grappling, Fast Movement + Cunning Action for superior mobility, Feral Instinct + Brutal Critical + Assassinate means nastier surprise rounds...
