I never (ever) used a tad to mind control, never ate one of extra pods, and tentacle dude from a prism still said i need to transform further and gave me a frozen super-duper pod to do so.
never used it, have no intention to.
act 3, never had ANY consequences to not eating tads.
Seems like exactly what I predicted. You get huge benefits from using (and now eating) the tadpoles but squat from refusing to do so, which is utterly lousy game design.
No, it's amazing game design. Behaving with Wisdom and from a desire to do good is undermined if a reward is expected. The standard has always been "Be a goody goody and the game will be easier because you will become super powerful"
Larian turned that nonsense on its head by saying "Look, the path of goodness and Wisdom is a hard one, you are giving up power to keep yourself whole, few have the strength to walk this path"
And yeah, I am walking that path right now. On tactician. No shoving, no illithid powers, no evil bargains. It's really not a problem - you are easily powerful enough to take on any challenges.
Good used to be a path you ambled down because it was the path of least resistance. Now it's a mountain you climb to reach a summit. Goddamn brilliant.
