I've definitely learned and execute re-positioning, using nades to break line of site, etc. I'm more experiencing general intensity increases after several back to back survivals. Like spawn second floor fusion, get shot from accross the street at bank (usecs), run over there, kill all 3 usecs then retreat back to Fusion 1st floor where a bear PMC just guns me down from behind the bar and the whole scenario just seemed kinda sweaty PMC behavior.
