Gotta remember that fluxes are also anti shield AV grenades, they can't simply do anti infantry levels of damage.

I think fluxes should be left as is, yeah shield heavies are hurt for it, but those who use it are denying themselves easy kills with the Core 'Nuclear' Locus.

I'm a proponent of changing laser damage profile to +15%/-15%. This would help to balance shields and armor but would leave a gap at the extreme end to match explosive damage's effect on armor. Right now flux grenades are too powerful against stacked shields, especially Caldari sentinel. If everything else changes to balances shields with armor but flux grenades don't change, Caldari sentinels will still be unusable.

My solution to this--and also something that will give shield tankers in general some breathing room--is to change flux grenades so that they do a tiny bit more damage than locus grenades, with a damage profile of +20%/-20% (the opposite of explosive damage). So they now would damage armor about the same as locus grenades damage shields. On the other hand they would still tear up shields, but wouldn't just make them disappear 100% of the time. This would enable Caldari sentinels to stand and fight among the explosions--which all other sentinels can do--and keep shield tankers in general from having to abandon their position after getting fluxed.

But there's more! There needs to be a weapon, not just a grenade, that uses this damage profile...one that can be used as the go-to AV weapon against shield-tanked HAVs, but which also can be effective in getting some splash damage against clustered enemies and devastating direct hits against heavies that fail to get out of the way. Ladies and gentlemen....I give you.....

The Flux Cannon!

Switch the plasma cannon to the new flux damage profile, increase its projectile speed, give Gallente commandos a damage bonus to flux weapons as well, and bam!!!--we have a working anti-shield HAV, anti-low flying shield ADS AV weapon! And with the increased projectile speed it can be used against logi train heavies and choke points. AND as shields and armor come further into balance it can be tweaked (or an assault variant created) to make it more effective against shield-tanked infantry, if the time comes when shields have been a bit over-balanced and need a counter.
