In all honesty, if i do the expert roulette and see a tank not doing W2W, i'll probably be slightly annoyed. Like others have said, the majority of players do the expert roulette every day to get the rewards, and when you've done the two same dungeons dozens of times, you'd rather finish it as soon as possible.

That being said, it's only a couple minutes of my life, so i won't even bother bringing it up, and i'll surely not start insulting a tank for not doing W2W ... People acting like this are ruining online games and you should just report them without hesitation.

Just know that in expert roulette, W2W pulls are pretty standard
