And Travail suggested this:
Looks solid. I’d change up the runes a little, at least for sPvP. Keep 2 Strength, but then have 2 Runes of Fire, and 2 Runes of Hoelbrek. The 40% extra might duration is better than the 5% extra damage, IMO (I say for sPvP, because there should be other ways to get extended might duration in the open world.) I’d also switch up the Soldier’s amulet for the Knight’s in sPvP; I’m not a huge fan of the toughness stat in PvP.
You can use your block/Elixir S to defend against burst, and toughness doesn’t do anything against conditions. I’d rather have the higher crit chance, for more devastating burst damage.
