Arenas Shouldn't be an LTM

In a recent Q&A they answered that it's currently an LTM purely to test engagement and to see if it's worth to implement it as a permanent mode in the future.

Q: Will Arenas come back permanently?

A: No, not this season. We're bringing it back because people asked for it. We wanna see what the response is. It was more work than it was worth when we first had it live, because it wasn't getting a lot of traction. If we see a lot of traction and a good response, we can talk about how do we wanna bring it back? Right now this is like a test run to see what the engagement is and what's working and what's not and keep tinkering with it.

I personally really love Arena's, and it's pretty much the primary reason for playing the game.
I'd understand their reasoning, if the game is barely getting any attention from the playerbase, and it takes a lot of effort to maintain it, they wouldn't really have much reason to keep it.

So if we want to see it in the future, I think the best we can do for now, is to play the LTM a lot to show we want it back as a permanent mode.
