Skipping battle grounds for that last 20 dust

I'm debating skipping the last 20 dust. I personally don't like battle grounds. I think it takes too much time to get through one match. To get the dust it takes minimum 32 matches assuming you win 5 in a row and then win 10 in a row. That means using 480 energy if you use energy for each match. My thinking is that it'd be better to spend that time and energy in quest and arena to get units for cyber weekend. Any thoughts on this? Should I just make myself do battle grounds for the dust instead?

There's more dust coming next month. And the month after that. And the month after that. Et cetera.
Don't do stuff you don't want to do, in spite of what others may pressure you into. I'm fine with my decision. But you do you.
Also, since I started in Plat 1 by the time I got to Diamond 1 almost every opponent was 4-5 mil+, I just started using energy and quitting out of the roster was too jacked. Found some closer to mine or only slightly higher and played those out for the 10 wins.
But if you can suffer through, it’s worth it. The 30k of Hercules sitting on my roster says so.
They never said dust will be available next month, i wouldn't let the opportunity go just in case.
I was going to do it regardless, since I want the BGs tokens, but it wasn’t as bad as it seems, for me at least.
Hell, I just did the ‘win 10 matches’ final objective earlier this morning, and 8/10 of those, they forfeit right away, so it took me next to no time to get the last 2 wins in.
EDIT: S3, not S1
