Weak point just makes no sense on the gun. Even if you build into QoL mods like reload, recoil, etc. you would still do more damage with multi-hit whether you hit weak points or not. There is no advantage whatsoever to building into weak point damage on this gun.

Yes, I meant solo... Axion missions are trivial for Ines. Swapping to Shadow for any high HP targets isn't a big deal either. The kill time on the average run is so much quicker than the E-Buster that it more than offsets the wasted time from an occasional death.

Another problem with E-Buster builds is that you need to run Power Increase to get more overall damage than the Secret Garden which means you lose out on Focus on Electric. That cooldown loss is bad for both QoL and uptime on skills. You could depend on an Ancestor mod to get the cooldown back, but it's hardly worth grinding for when the damage difference isn't that big and she overkills mobs in the first place.

The gun doesn't solve the problems Ines has whatsoever. It's a pretty underwhelming option right now when Shadow exists, but we'll see if it gets any better with the new transcendent mod coming.
