I've noticed that I get more trash per hour not using an elvia weapon.

From what I've seen, using the elvia weapon and killing either causes the commander to not spawn any enemies, or sometimes their death will spawn the naga back where the commander usually sits. It also ends up spawning less naga. I've also seen the death of a commander despawn mobs now too. This all only happens when using the elvia weapon.

I'd like to see this interaction fixed, it's holding back naga from being a great rotation.

tag all 3 commanders, wait until they spawn the little guys and then nuke everything down.  Also you may get "more trash' from killing the little guys, but the commanders have a higher narc's lightning, seed of the void, and moon's split nail than the little guys do.  Unless you are killing the commanders faster than they can respawn not spawning the little guys isn't all bad.  

Even that is less little guys than without the weapon.

The spot I grind isn't devoid of commanders and their respawn timer isn't bad. My problem is I don't make up that loss of money from the lower trash with the few extra rare mats I get & I'm missing out on the extra trash I should be making with elvia wep clear speeds.

This isn't an issue at other spots, you get more trash and more rare loot at bloody monastery with elvia wep as an example.

Getting the same amount or lower trash loot with an elvia wep as I would without one is a net loss to me.

I'm not asking for much here, just the same expectations an elvia wep gives at other spots.
