So use them yourself. If everyone has access to them there can be no complaints.
Durability is a somewhat broke set of runes. The only thing that counter balanced their effect in WvW is that it was a bit of a grind to get them. My hope is that with or before this change goes into effect, ANet nerfs those runes. They are OP in skirmish/zerg fights… IMO.
If you haven’t run into a skirmish crew running bunkers with these, just wait. Our bunker tempest is at a 3v1 level right now. Add in a second bunker and it can easily take 8+ to bring them down.
the rune is not the op thing cause of its 20 sec cd, the more broken and skillles thing is boonshare, THAT IS THE REAL PROBLEM THAT MUST BE NERFED HARD (but thats a problem for over 1 year and anet’s balancingteam dot care about it)
