I do have Forest Guardian but without the last two traits. I have no Arcane Light stones and can only make 5 easily in the Soulforge. My Fenrir has no traits …maybe it was the lack of Wulfgarok which stopped me developing those troops … but I certainly have not been using them hence the lack of buffing on them.
My last battles have been with Mang | Hellcat | Stone Shaker | Giant Spider. But that line-up is starting to wear thin. I see my next level has three towers in the opposition team. So if multiple towers get barrier something that hits all enemy troops will be handy. Time to look again at the GoW bestiary … and maybe Fenrir & Forest Guardian will figure even without all their traits.
My Orb of Chaos was Ascension … which will no doubt come in handy at some point but the Trait one would have been great right now.
