I would personally rather see the recoil nerfs on the orion/SVA undone in exchange for getting a .5 ADS multiplier, and for the Betelgeuse to get 5 more rounds before overheat in exchange for .5 ADS. Not to "nerf the vanu" so much as to close the gap between HA and other classes. The HA is still the front line beater, but that should be more of a guideline than a rule, I am not a fan of "hard counters" either. personally I would see the shield changed to 300 damage absorbed and 18 second cooldown maxed, which is actually more shield recharged per second than the current one thus better in the grand scheme of things but not such a big impact on any individual fight while still providing a clear advantage that says "I am the class for this." The NS15 can keep the .75 ADS multiplier because what it gains in survivability it trades in raw DPS/TTK so it doesn't leave you additionally advantaged over other classes.
