I get the principle, just not the finer points. Like, take Thundurus:

Despite high attack, he has even higher special attack, so that's his purpose. So, buff special attack or speed? Both are already obscenely high. And then, out of the rubbish stats, what do I pick to knock down even further? HP, Defense or Special Defense? Defense is his worst, so that? Or perhaps just debuff attack, sparing his weaker stats, as I won't be using attack?
Like as far as I see it, there are
options here, man.
