It's the middle of Season 6, and in this season we did not receive any new armor. I believe the only new armor in Season 5 was the even armor. I know it's (supposedly) tough/timely to design, but I think it's worth mentioning with a couple campaigns to go - new armors in Season 7 PLEASE. I'm not bothered by the repetition and spikes, but we need more variants to loot to keep the experience fresh. Many of the heroes I play are Rep 13 or higher and I literally have access to every armor piece.
Considering the time it takes to go from rough sketch to complete 3d-model I believe I can safely say that if we are getting any new armour types or weapon types soon they are already in development. Considering how impatient everyone has become since the E3-reveal of all the new stuff, rest assured that any project started by this thread would not see completion soon (tm).
