All I hear is people complain left and right about the tadstones but what about it is sooooo annoying? It was easy, the swimming controls were fine, and it was relaxing.
Your opinion is not fact, sir. Everybody had their own opinion and nobody's opinion is right or wrong. Perhaps people complain a lot about it, but you don't have to accuse them of, what, being too lazy and stuff? The controls may have been easy for you, but for some other people, the controls might have really been screwed up. Why is it so annoying you ask. Well, correct me if I'm wrong, but the main reason was the swimming part and the swimming controls. I've played through SS multiple times and each time gathering the tadtones were either easy or hard.
For a lot of people, this tadtone quest may have been really intense as you have to swim throughout the entire Faron Woods to gather a large amount of tadtones. Running out of breath is a very easy task to accomplish, there are those Brainioc's that attack you, froak and when you do that spin-thing, it all takes up a lot of your breath.
To me, it sounds like you're complaining too. The tadtones were an extremely tedious task and it might have been a little intense for a main quest requirement, perhaps better off being a sidequest. Nonetheless don't accuse people of complaining when you're technically complaning too, it's hypocrisy.
