You are not trying your best to win if you pick a champ in ranked that you have never played before. Simple as that.
You're right. I apologize for the unspoken aspect of my statement. I felt it was so evident it didn't need inclusion, which was obviously a poor decision on my part. Allow me to correct it:
"But first-time picking a champion in Ranked, and trying your best to use that champion to win is not intentionally trying to lose the game."
I'm failing to see the difference in your AP Riven example. You say "making decisions that are known to be poor", how the hell does picking a champ that you have never played before in a ranked game not fall into that category?
AP Riven is impossible. She gains exactly nothing from AP on any skills, so all the gold she spends is wasted. It's not that she doesn't work, it's that she can't work.
Picking a champ that you've never played before - but may have a decent grasp of, conceptually - because (for example) it's a hard counter to your lane opponent isn't impossible. It's perhaps inadvisable. It's probably not the best plan. But it's fully possible to still do well despite that inexperience.
There is, after all, a difference between "making less than optimal decisions" and "making decisions that are known to be poor." If you're saying the former equates to trolling, then every player is a troll.
