1.) Martyr Paladin - the flavor of a holy warrior who takes on the problems and injuries of his allies for himself is very cool and its a type of paladin you cant really make without the archetype AND the core mechanics here are really amazing. You have the ability to bleed stigmata tp inspire your allies (this currently gices them bardsong in place of Smite Evil but I think this could be tinkered with), the ability to take on the afflictions and statuses your allies have and the action economy to do this while being relevant in combat.

More importantly though, it's a healing forward paladin that doesnt feel like ita trying to be a cleric - its hard for me to explain but it feels like a very Paladin way to heal and that it specializes in afdlictions gives it a niche that clerics struggle to fill sometimes. This is hands down my favorite archetype all around flavor and mechanics.

2) Cloistered Cleric - I really dont like the way this one was implemented in 1e but the archetype of kind of Catholic Medieval monk is a fictional archetype that payhfinder doesnt really capture elsewhere. It would be really cool if this concept could get an awesome representation in 2e. Perhaps they specialize in haunts rather than more traditional kinds of undead?

3) Carnivalist/Sczarni Swindler Rogue

In my mind these concepts are sort of linked - I would love to see a social swi dling focused rogue based on the idea of street performer/grifter. These are two of my favorite archetypes on spec and it would be great to see revamped rogue really be able to nail this concept.

4) Mooncursed Barbarian - I love love LOVE the idea of being able to legally play a chatacter who has contracted lycanthropy without being a disruptive presence in the game and I love the idea of rage and lycanthropy being linked. This is a very clever and fun archetype in terms of both flavor and mechanics - Beast Shape in many ways emulates the benefits of rage anyway but being so mad that you turn into a bear is awesome. Keep it please.

5) Lore Warden

I think you need only reference the INCREDIBLE backlash to this archetype getting tinkered with to see what an emotional attachment the organized play community has to this concept. The idea of an educated fighter who uses a finessed fighting style and who is a scholar is something pretty unique to the lore warden (only the Armiger comes close and that's another excellent archetype).

I would love to see the idea tinkered with, maybe trading some of the 2e fighters amazing action economy for improved finesse options. Just spitballing here.

This was very difficult to do even just sticking to core classes and not even getting to talk about Inquisitor Oracle or Cavalier let alone the Occult classes!
