Is picking Dianna bot/adc consider trolling?

So its dynamic queue, you know you are going to be in that bot/adc position. And you pick Dianna. That is trolling right?

What makes it worst is the player is a Diamond player from last season in a normal game, so yes that said person would still win the lane due to the skill difference. But that just ruined the game for me and the rest of the oppenent team. (I am on the Dianna team, we won the game. But it has little to do with strategy or picking correctly.) Its like a heavy weight wrestler join a small time local club tournament just to act all high and mighty and beat up all the contestent.

I shouldn't have to sit here play a game with a player way out of my league in terms of skill level and cooperate with his/her shanagans/troll pick. I just want to play a simple normal no troll pick league of legends is that so much to ask.

Edit: So it seems the general concent is, it is ok to pick off meta pick. As long as you win. The problem I have with this is you would not know if you win or not until the end of the game. And this is result oriented, not cause oriented.

For people who would not mind off meta pick just because it says, "bot". Yes Riot try to add in diversity in the bot position, so they tried with Mord. The experiment of Mordikasier has come and gone, in an objective sense we can all ask ourselves has it worked out? Just look at all the data, it probably is no. "Bot" is still really an "adc" or more accurately "marksman" position. Statiscally, a team needs to pick a champion in the team with some range auto attack since teamfight and tower seiging is much easier with one such carry, and it just so happen that carry goes to the "bot" position. Currently as it stands, its gimping your chance of winning by picking anything of not marksman at that position. If you want to play a Dianna bot game, you can just get 4 other players with you who also loves playing Dianna bot and make a team around that.

And let me ask you this would you want a dianna bot at your rank game? Probably not. So why would I want a dianna bot at my normal game? And if you want to say "you try hard in normal? you are silly". Yes I try to win my normal games, don't you? You would not go into a normal game and be like "hmm I want to lose this game now".

That aside, I have no problem with breaking the meta for a strategical advantage. But in this case, it is someone doing it not because of that, but rather with a superior skill level to pull off a stunt and force others to cooperate. It is certainly not fun for the oppenent team facing a Diamond level player. And it is not fun for our team to cooperate with someone just so we do not lose and waste our time playing a hopeless game.
