I liked Ana when she first came out. As a matter of fact, I thought Ana was amazing, and I was very sad to see how the community treated people who tried to take her into competitive. What I said was most people would troll if their teammates picked Ana. That was so far beyond acceptable to me, and I didn't want to deal with that.

As for being repetitive, maybe I'm biased, but I feel a League game can be very different based on the heroes picked, but with less heroes in OW, most games felt pretty similar.

Charge up ult, call in on VC that your ult is up, everyone ults at the same time, with some variation of who is ulting when, and then you try and crack the point.

I was a decent enough rank too, so I don't think it was just noobstomping. I almost never feel like teamfighting in LoL is just all of your team hitting R at the same time, but I do feel that way when I play OW. Not to mention that in League, you can spend all game in just 1 or 2 lanes of a gigantic map. In OW, you run all around and the maps are kind of small (And some of them, like my favorite map Hanamura, have these really strange side lanes that lead to nowhere and literally are a waste because nobody is ever there.)
