also, yes strategy is part of the pick phase of matches, but like
are you that worried about this ever happening? the matches that you get to match point immediately, you're almost 100% expected to come out on top.
if you're at match point and manage to lose every single map until the tiebreaker, then the match should go to tiebreaker. If you modify your "strategy" appropriately then that logic still stands. It doesn't eliminate any part of strategy aspects, it changes it. You're saying that only because your particular strategy is being removed as good. The other "strategy" if you're willing to call that tiny bit of picking "strategy" just becomes the better strategy. You can still save your strongest pick if you want, it'll just be a bad strategy
in all, in my opinion, your complaints are kinda resonating as "I'm worried about losing"
