Yep, agree with everything you are saying here, including the part about HoW exotics being along the lines of HoW Legendaries instead of earlier exotics. The only issue is, like you said, some of the really important details are still missing. My understanding was that any of the Legendaries and Exotics would be upgraded straight to HoW levels, and that re-Xurbishing was going the way of Commendations and the Dodo. Hard to be certain since the stream was so unclear, like you said.
Btw can the Iron Banner gear be upgraded to 365 / 42 Light levels as well? Have they commented on this at all and I missed it completely?
Yeah the "mesh networking" or w/e, with Destiny's server + peer-to-peer hybrid system, can produce some bizarre results that become very aggravating in PvP. I really want to get a nice gaming monitor to reduce at least one source of lag...
Which crucible bounties are especially irritating? I'd definitely recommend to either not bother or space them out over a few days, at least to me however much XP they are isn't worth the headache if it's not fun at all.
