This super feels sub-par right now, at least compared to its predecessor. Couple of things which might help it:
-Increase damage (PvE and PvP)
--PvP because some enemies survive even though you have hit them with a blade. Happens too often. Increasing damage to 300 might prevent this. Currently sitting at 205.
-Allow each blade to cause scorch (+60), fire trail (+30)
-Increase duration, allow each kill to add super energy
-Rework Dawn Chorus to how it used to behave before or substantially increase burn rate damage against Bosses, Majors and Minors
-Increase speed of blades (similar to harvestor)
-
Overall PvE damage needs to be waaaay higher. It's pitiful right now and completely behind the other Solar 3 reworks. With exotics, Bl. Barrage is iro 680,000 Daybreak is iro 280,000 for example. Blade barrage needed it, so don't nerf that but bring up Daybreak quite a big bit.
