Two buffs I would like to see is the max distance between nodes is bigger, and any nodes in the pylons radius are indestructible.
Max distance between nodes - there is many choke points on worlds edge, and it’s disappointing to see that Wattson’s fences don’t reach the full distance. This means you have to place 3 nodes to create a fence that covers the choke point. However, even if the two end nodes are hidden, the node which is in the middle can be shot, instantly destroying the fence and making it useless.
Indestructible nodes - the nodes are to easily destroyed so yet again making them useless. If they were indestructible while in the pylons radius, it would make them more useful. Enemies would have to destroy the pylon first before destroying the nodes. (Crypto’s EMP could still destroy nodes).
As you suggested, I would like to see her fences do more damage, giving players a reason to destroy them or to be frightened to engage.
This would also make for more exciting battles, Wraith could create a portal, phase through the fences then open her portal on the other side. Octane could place his jump pad and the team could jump over fences (in open space obviously). Or crypto could use his EMP.
