Is a Wiggs Chaze R2-D2 team still viable in lower ends of arena?

I think just playing is viable at that level. I imagine a lot of the teams at below 1500 are inactive players.

But I haven't dropped below 100 in months so hard to say for sure. But even when I ran a cobbled together team based on my highest characters and only ran 1 battle a day for dailies, I stayed in the top 1000 easily.
