I don't really have much more to add, I doubt you are playing "better" opponents because better doesn't really exist unless you're managing to only play in prostacks. Even if you are, the build isn't suddenly bad because people know how to click their armlet. Also, if you want an example of how bad orchid is go watch navi/EG that was played a few days ago, their orchid clinkz did absolutely nothing the entire game because he didn't have the damage for it.
A hero being picked constantly could also be a sign that he's well balanced, being useful in all situations makes you well rounded. Winning 90% of the time you're picked makes you broken.
