Things I'd wish I'd known when I started playing SWGOH

I wish I had known how important zeta abilities were in arena from the beginning. For too long I put off getting the dark side ships needed to get Executrix to 5* and unlock the fleet ability challenge. And that meant most of the top 50 in my arena shard had zeta abilities before I started to farm them.
Something I have kept in mind, though, is it’s possible to overcome most deficits with time and focus. And that has helped a lot with staying in the top 50 without spending.
