What’s so bad about deci banshees (I’m not trolling) seriously?
All the passive buffs they get from Deci make them, faster, better, stronger, tankier because of the healing and not to mention the second stronger from killing frenzy.
Add on top the siphon and fury abilities and they destroy any unit they come across.
Not to mention Deci gets a lvl 3 glassing beam which deals with any 'threat' (using that lightly) to the banshees.
To go somewhat in depth: The added speed means they outspeed glassing beams, abilities or the wolv which could chase it. I don't think I need to mention why the 2 passive damage boosts are a problem. The siphon is too powerful on them. If you use an ability and almost kill many of the banshees, they'll heal right back to full iwthin a couple of seconds of combat. effective negating the ability you just used on them.
