Good points. There are high-scorers in the MA whose ACM is pathetic. Essentially they play the arena.
With the ACM-focussed players it's not so much they have poor SA but they start a prolonged fight with two cons and a third and fourth show up and breaking off the earlier cons makes no difference at this point, you just have to make them all work for it. Don't do that if not getting much practice at landing or smack-talk bothers you
Why don't you teach him the BRD Violator?
Yup, the gang is the worst nightmare for us who enjoy a duel. No reason for 3-5 to be on one plane anyhow
that makes the MA extremely difficult for the amount of time it takes to get to the fight and why it's so important not to chase and get tangled up in a stupid situation.
Here is a quick basic BRD video. A really good one to practice. It's really easy to practice this in the matchplay vs the bots.
