How much can you "break the meta" before its considered trolling?

Lets say Smite Support Nunu locks in and gives the spiel of what he's going to be doing in champ select.

The community is in agreeance that this is not reportable correct?

Now your ADC Ashe grabs smite and declares "I am going to be supporting our support. My goal is to ensure the safety of our Nunu while he counterjungles. I will be maxing E first to provide more vision while we invade. I will be rushing sightstone to establish more vision in their jungle"

Is this trolling? They did the exact same thing as Nunu. They explained exactly what they were going to be doing in champ select and their strategy for victory right? So you we would have to say Ashe is not a troll correct?

Your Mid Syndra now grabs Ghost and Tp and explains "I will not be going Mid. My role is roaming mage. I will be roaming to assist teammates around the map. I will be rushing Mobi boots to maximize my roam potential"

Is it trolling yet? According to the terms we've established, this is perfectly acceptable. Assuming Ashe and Syndra don't flame or int, they're doing absolutely nothing wrong correct?

You now have a game where there is nobody in Bot or Mid lane. This is acceptable according to the terms we're establishing right?

So someone explain to me where the line is? Because what we've established is that you can't punish trolls as long as they're telling you they're going to troll in champ select lmao.
