From mid 93 start of the event to low 95 now. Actually, not been a problem. Was hit a few times early on but have defended all but one attack and lost just two medics all week! Read elsewhere that probably safe enough until about L98, so long as keep allies under 498. If and when I get the final warhead, gonna find a nice little campsite and chill like a mother for two or three weeks, or until the next event!
