The way we`re doing it, is we have healers running on the ground and our ussual setup is a sorc and an operative healer. For sorc it is very easy - just pop your shield on you and if you get "Absorbed" message - run away from that place. Shield would be able to absorb 1-2 hits from lightning. For operative (and really every1 else, inluding sorcs) - just move couple meters every 3-5 seconds. The lightning rods always take up the same space, so they are easily avoidable by correct movement and positioning.
Thanks for adding this tip, it's really helpful for people to know how to get around the plethora of bugs at the moment.
