What the recent history in which they allowed the ascension of year one gear? Exotics will be ascendable, that much is a concrete certainty and I honestly can't see them making vault of glass and crota even more irrelevant than they are currently because at the end of the day, why would anyone want to run those raid if the gear was utterly pointless? The evidence is that the new level cap is going to be 50, it will at the very least be 10 levels above where we are now so the weapons will be increasing by a similar level which would make any weapons stuck at current levels utterly useless
