Will their be two versions of exotics (pre-expansion and post expansion) of the same weapons? Example I received an icebreaker from a nightfall last week with pre-expansion stats, but next week I receive the post expansion version of the icebreaker with higher base damage. If so what is the incentive to pay almost one third of my total glimmer I am allowed to carry plus exotic shards plus strange coins to reset my current icebreaker and start to re-level it all over again? (other than time and patience that it takes to acquire the weapons over again)
