After the patch came out i recognized there arent any savespots in Chaoscave from now on.
Fact is the mobs now shoot your head if they see it(before they only aimed for your feet - feet save character save).
I dont know if this was an expected change in the patch since it makes chaoscaving more difficult for non aoe/droner classes.
2nd thing is i got shot by firemobs through environment(grim chasers normally dont hit you if their right hand is behind a wall). Had it also once a mob started clipping through walls as well. Network statistics where good, so it was no latency or packetloss issue.
More testing i cant do - all my chars arent capped got no rares and LE in currently. so pvp is pretty senseless
