Please help me understandimg. I assume everyone is running new armour cause it has way better stats than the old armour except for exotics. I see a lot of players running new weapons as well, exotics again the exception. Personally I still use predominantly old weapons though I swim in new ones. Bottom line I am upgrading new armour with same new armour which is glimmer only. New weapons the same. Hence unstable cores I require for upgrading old exotics and old weapons and I get enough unstable cores by dismantling unwanted/bad rolls resp rolls sitting at/below PL. I admit I completely stopped playing my other two characters but less to a lack of upgrade materials than I can't be bothered to run three characters through the repetitive PL grind. Aside from being tempted to upgrade a whole vault to current levels - which I don't/won't do - I don't see an issue with the availability of materials at least with regards to glimmer and unstable cores. Ascendant shards are a constraint with regards to upgrading armour - 3 for tier 5s - and most likely everyone not having farmed enhancement cores will run short on them quickly. Long story short, ascendant shards and enhancement cores are Imho the current limiting factor.
