It appears that the Borg now have rather absurdly high shield penetration in STFs. Without ever losing a facing in my shields, my battlecruiser ended up with 10% hull left at one point. What is going on? Is this a bug? Is this intended? It feels really wierd to see your hull falling apart while shields aren't even below 50%.
I haven't done an STF yet since Season 7 started, but I did a couple of those Borg Alerts and have never had as much trouble as now. I'd go from 100% shields/hull/crew to dead in less than 2 seconds - and I'm running MACO Mk XI.
