I'm wondering if upgrading the circled choke point (B-Coin Mixer) by a few levels would help improve the defensive effectiveness of the Al Beetle. Because if the HP is too low, it might reduce the Al Beetle's effectiveness since it doesn't have enough time to repair it before the B-Coin Mixer gets instantly destroyed by a or

If this theory is correct, what level would be the most suitable to upgrade it to?
