I recommend prioritising upgrading dual element EpicBoss+ armors. In the long run, you'll discard the non+ armors. Don't get rid of any armors just yet, since they may help with epic bosses for the time being. The general rule of thumb is never to combine or fuse off an armor unless you won't miss it for sure.

As for arena right now, stick to whichever ones have the highest stats ''when equipped. ''
