Ehy Spartan =) You're right, indeed. I hope to see a refresh of Tower's Vendors stock with the New Season too. However, I don't know how likely it will be. I think that Bungie clearly prefers the "Tokens" or "Materials" system to keep players "more engaged" [i](aka, they will grind more, so they'll play more)[/i]. I hope to be completely wrong and see Bungie doing the "right thing", but... after all this years, how stupid would be to still have hope on that?
Before armor 2.0 those planetary armor didn't have any elemental protection on them so they didn't use to be that good, and I guess they just kept it around after 2.0. Imo it seems all planetary armor will be sunsetted and perhaps removed? i might be wrong but all those armors have power lvl 1060 only...
