I was taking a look at the new Ranger archetypes, and I was stuck with this idea: Why go Horizon Walker over Gloom Stalker (Damage wise)?

The Planar Warrior seems strong on a first glance for me, but I'm not sure the Bonus Action economy works quite well for it. Yes, I'm aware Force is a really good damage type, and that you can use it indefinetly as long as you're at 30 feet of the enemy.

You have to be kitting the enemy really well to use it as an archer, and if you face multiple enemies, you kinda have to choose between Planar Warrior or moving Hunters Mark to another foe after killing the first one.

The added spells are really good, but the other features not so much

Detect Portal is REALLY campaing dependant, and if it doesn't fit on it, you can rarelly use it. Ethereal Step is... OK I guess, but not that great either. Spectral Defense comes REALLY late, but it's good if you do play that far...

Also, I have a bad time thinking in a backstory for it... So, sell me Horizon Walker please
