Well i just finished Honor mod with 4 pt members. No tadpole no cheese no cheat run no suprise no respec single class no prebuff.
So there are some difficult things but just a few. The noticeable bosses where : Spider queen / Inquisitor / Grym / Gortash /Ansur / and the Titan. Few of my companions or even the main character died in those encounters.
Medium difficulty I had with Myrkuls avatar+ Thorn and Nere.
Everything else was the same like in tactican there was no increase in difficulty really. I never saw anything " about the later encounters getting harder as the Honor mode description points it out" . Also traps are ridiculous in act 2-3 I don't even bother to disam them. I still had issues that I don't even needed to rest really and because of that I missed a lot of content.
But I think if I will play it solo and on the top of that i use the custom mode to get a - 1 proficiency bonus +x4 on camp supply and price of the merchants. Then I think even me with 3400 hours in BG3 will be challenged w/o tadpoles ofc.
So this is a step into the rigth direction but only really challenging in act1 and actually act 1 was not so bad in tactican.
So as others said before me Honor is too easy but ( for a 4-3 man party). Enemies don't have armor class so they got hitted 90% of the time this is really a joke. It doesn't matter if they have 18 or 10 if the average to hit bonus of any lvl 12 character is around 14-20 + advantage. I also think the vet effect is to strong. This was the first time I used sorcerer and tempest cleric but it's insane VS this classes Paladin or tavern brawler monk is a joke. Most of the time I just skipped the turn of Lazell (sorc) and shadow. H( tempest) because if the act first!! there is nothing left to experience from the encounter.
My personal opinion with honor + custom mode it's challenging for 1-2 players. I tryed to give a spoiler free feedback but as I moved to act 2-3 I was dissapointed because Ac1 started so strong.
PS If I could influence the dev team to make a change.???
Then my suggestions are the following X3 more trap damage.
Moving objects or talking them out from inventory should cost an action or bonus action. In both divinity 1-2 it costs points to move an object I don't understand why here don't. It's ultra unrealistic. In this way the carrying capacity makes no sense why is it even present??
Its insane that this is even possible.
I also think that trowed potions should not effect multiple targets and it should use the complite action instead attack / round. It's so stupid that a figther with action surge can bring back from a death door state the full party to a maximum hp with just throwing potions. And he can trow at least 6-7 potions .
