just to be sure that im doing it right on the exploding nodes, i get close to shorten casttime, i go boom, do a nice little corpsrun, do the 10 sec cast or rather the 9 sec cast as node despawns with 1 sec cast left, i mount up and fly onto the next node. is that right or am i missing something? Have fun all 
I mean, you could move and avoid the whole “going boom and corpse run”
No, you are not supposed to die. Avoid the red circles. Try landing on top of the node, and the red circle will not kill you.
you can invest some points into mastering the elements to unlock the ez-mine ring, even without investing into it should reduce bomb damage
I got the first ring of all trees filled before I started tackling subrings and its paid off nicely esp. for the special deposits
You can just move a little further away from red circle. You don’t need to literally closest to it.
