if you get a bad game even routine can end up as hard a heart breaker in terms of mob damge output and damge resistance, or at least it feels like it.
also I have noticed that sometimes the spawns start to feel totally endless, a quick tap on the font as you bowl past can reset the additional resilience of the faction your up against but it seems that only happens if the host taps it and has a good lag free connection....
played a game the other day as host on peri, had 3 guys in starting armour that kept ressing each other after fadeout through the use of Templar /mage lifeward passive,
I think by the end of zone 1 they had all faded 5 times each (lucky me I was on the ss) the only good thing was the mooks stopped getting any harder as if they had hit the fade out increase cap for the game but it felt worse than soloing hb against venatori with all those mages (we were against demons and luckily after zone 1 no wraiths) zone 2/3/4 all went the same way lifeward kept picking them up and letting them hit stuff until they died and ressed their buddy, if it hadn't been so tragic it would of been epically funny, made me work for that dragon that took an age to kill in the final zone still I did get a full set of highland dirks at the end of the game (6 of them....)
I have no idea how its meant to work though as sometimes it seems like they get easier to kill when people fade out rather than harder (certain hosts) but they definitely get movement speed damage and defence rating boosted with each fade out from what I've seen happen
