Open world PVE mostly.

Guardian used to be my main and favorite class but I've recently been having a lot more fun with Warrior and Ranger. My Guardian seems underpowered and is extra squishy once aegis drops. I'm in mostly berserker gear (with a bit of vit and tough from a few off pieces like helm and trinket) and running either Power Willbender or Core Power DPS). But I'm finding that with the expansion content, my Guardian just doesn't hold a candle to my Warrior with Spellbreaker or Bladesworn setup.

If I use the booster on the Guardian, it's probably to try condition Willbender or Firebrand with the Celestial gear. Honestly an attempt to salvage what was once my favorite class from what feels like mediocrity now. It'd probably be better if I did more group content, but it's mostly just roaming with me and my wife in open world.

The Revenant is new to me, but seems really fun, I'm still leveling him. I assume torment scales with condition damage and Revenant seems like a good choice for the combined stats on the Celestial gear. Really like the mace skills and throwing hammers at people is a trip. 😁

I'm leaning toward using the boost on the Rev, but I'm torn because I love my Guardian. But the Guardian lately has just been a crafting mule. Celestial gear is hard to come by so I don't want to waste it if I end up not playing it. He's already geared for power. Plus, I hate scepters/wands. But I wanna get this booster out of my shared inventory slot.

Can anyone list pros and cons for these classes with condition builds and specifically Celestial gearing?
