I try to wait before self reviving, but if there are too many mobs about I will use it or if nobody is close/running towards me. Then again I rarely get downed during arkfalls (unless I solo one where there are tons of blastpods and archers).

Rolling with the Red Thugs!
I went down a few times this morning and felt a little used when a horde of people came over wanting some action, but I felt better a short time later after a little reciprocity and finally gettin' mines. Only a few more to go!
if downed players showed as another colour on the minimap that would make things so much easier when trying to spot them, maybe yellow or something.
