This is an interesting topic, after reading your previous posts about the failure of Defensive stats in PVP, I respecced and equipped a DPS set of PVP armor/items that I've built up through extra unassembled champion items. I remodded the rest I couldn't replace. Trust me, after building an entire set of Champion Supercommando gear, it was painful to read your findings and remove my beloved tanky stats. I have saved the mods, just in case. I tried it and while I have noticed a certain increase of squishy-ness, the DPS is greatly Increased. It's not rare that I will go 200K+ dmg and 80k+ prot now. I would barely break 100k damage before, although I did get up to 160k+ prot in several matches where I had a dedicated healer. However, I will say that fully investing in that defensive gear and going deep into the defensive stats of Shield Tech did allow me to stay alive longer, especially when getting attacked by 3+ people. However, I couldn't kill any of them. lol. So while the defensive bonuses are good, I still think that the hybrid ST/Pyro with dps gear is overall a better value. Therefore, unless 1.1 brings large noticeable changes, I don't think it will effect the viability of a hybrid spec in pvp. TL;DR: Unless 1.1 has a very big and noticeable change in defensive bonuses, it probably won't be worth it.
