I mean, the title is "Medicine most OP skill in the game", also even if it actually is the best final skill, taking the perk makes it so much harder to level medicine further.
Okay fine.
I hate tactics skill and perks as much as the next guy, believe me, but both the perk tree and the final perk itself is better than medicine final perk. I could also say, I don't count medicine because -reason- therefore it can't be the best final perk. That's not an argument. I think that having a skill tree devoted to auto-calc is incredibly stupid and unfun as well, but it's still better than medicine final perk. Let's not forget that faster map movement through scouting benefits all gamestyles as well.
It's not silly strong but it snowballs very hard, but again, it's a playstyle difference so whatever.
I have tried it in several playthroughs after medicine leveling got fixed/better, it's still not as fast as you claim even on player characters with 10 Int & 5 Focus investment. And as I've stated multiple times, just picking the perk at 275 makes it so much harder to level medicine further. And don't get me wrong, while getting +38 health right out the gate is pretty great, it doesn't invalidate the whole game at all (it's already invalidated by the AI being terrible at battles and archers & cav archers being busted).
