I haven't had much complaint with it over the last few versions. The Banshee on the other hand...
I think it's more a matter of learning what Banshees are about. Yeah, the pattern is monstrous and scary, but once you learn how to deal with them they're not too difficult, I don't think. If you spot a Banshee, don't immediately just shoot because they never fire back at you until you fire at them. If you prepare for them -- and you can take this as far as clearing the room first before dealing with them -- you should be able beat them 9 times out of 10 without taking any damage. Attack, then run either behind them as far away as possible or behind some suitable cover, then just finish them off when they're zipping around.
I do think they need to be in a different category though. One problem is that they're appearing in some rooms where their attack doesnt actually fit properly (meaning, there's nowhere to move to in order to avoid it).
They're also super common right now.
A slightly higher category would help with both things. I dont know which one to suggest though.
Pretty much this. Killing them isn't a problem, it's the fact that a lot of times they spawn in small rooms where you have nowhere to run, or later versions that fill up a medium-large sized room before you can find cover.
There is a 3 section room where the middle section has a ton of pipes (you know the one). I was on floor 4 cruising around in the Flame Tank and took out a couple of easy mobs. Then BOOM, red tide...
Eat that one and move up to find red variant banshee in the middle. Nuke it real good and run like hell to find a TP pad... nope red tide death...
GG... bleh
