No Prisoner needs a lift - it doesn't do anything useful. I have never seen anyone take it.
Completely agree with above notes on Orderly and Heartsbane.
Enslaved Nephilim might be the worst totem in the game (see the discussion where several people would rather want a pass token and a card from heroic gamble). Instead of a Obey that is way too hard to cast, it should have abilities that synergise with the rest of the keyword. Like triggering A Por El regardless of cost, triggering Grit on others. Spotter (or better yet, a "reversed" spotter where it can let other models benefit from auras regardless of range).
Nino seems slightly overcosted - but not a full stone, so a little boost might be nice. +1 def or move?
Frank never seems to deliver the punch that henchmen of a similar cost in other factions have.
Pistoleros are a never take. They need to be able to actually do something useful.
As several people mentioned, Into the Cage on Brutal Emissary should have an extra effect (or at least a built in trigger) to make it useful.
I'd love it if Sonnia got Def 5. I'd also love a tome on her Def.
Thalarian Queller could also need a lift. At this moment, I do not feel that he can do anything other models cannot do better. Being able to Counterspell at a greater distance springs to mind. A melee attack would be good. I didn't start the fire not reducing burning would be great.
Samael seems lacking and overcosted, similar models in other factions do way more (i.e. Rusty Alice).
Risk of Reason on Judge seems harsh now. Either let them keep the tomes or reduce the damage.
I never played Dashel but that his summoning is nothing compared to other summoners is clear to me.
Frontiermen are a never take to me.
Austringers seem overcosted.
And yeah - Pale Rider might be powerful right now, but if he gets a significant nerf, Guild is left with more or less nothing. To me, he feels like a crutch model, not something overpowered.
It feels as if we are really lacking in clever tricks, ways to remove downsides, and movement capabilities compared to others, and this shows in tournament stats. If Guild is to be able to compete, they need a lift.
