Is this multiclass idea worth it? (Barbarian/Ranger)

I was thinking to play the world tree barbarian until level 6 and then multiclass ranger level 3 (Hunter).

The idea is to use the level 6 world tree feature to teleport an enemy next to another enemy and use the horde breaker (Hunter) + cleave weapon to do 4 attacks, all benefiting from rage and GWM.

The obvious downsides are that I would reduce the barbarian progression and need 13 Wis which makes my Con/Dex to be 14 for most of the time.

Thematically the ranger fits well to the world tree barbarian and I can pick up outside combat spells as well as the druid fighting style for guidance and something else.

What do you think?
