Yeah she seems fine, and that speed can always be ignored if she is actually tanking stuff.

Veronica a 4* has the same passive. Its pretty dope, since it works in similar fashion like AoE, but not quite.

The first one I suppose you got through gacha (dont wanna even imagine how much you dropped on that to get her with those odds, but since its you we are talking about, its not surprising at all ), but on the second one you got damn lucky, gratz.
From todays Invasion missions I got only few 3* and bunch of 2*. Hate the fact they changed that. No longer 3* and 4* now they threw in 2* as well into that mix T___T
She has what... 2% chance to drop on those. And you get 5-6 per day, with one reset, so thats 10-12 times chance to get those fckn 2% odds... ueghh..

So I tweked Ednas emblems. Gave her a Attack Speed one isntead of Movement speed. Damn She got very good. If it was a 5* Emblem instead of 4* and fully maxed, I imagine her reloading speed would be pretty much instant with no waiting time between the shots. Something absolutely crazy for a flamethrower type tanik.
