Pit of Heresy has always been my go-to for farming prisms and, as a concequence, shards. It is so sad that you decided to remove it, what an idiotic decision. “We want to make some destinations relevant again”. PoH has never been not-relevant. Give back the masterworked armor. AND ADD A THIRD MOD SLOT FOR SEASONAL MODS FROM BANSHEE FFS. Edit: A quick math: 100 days in a season mean more or less 14 weekly resets. 18 prisms times 14 resets are 252 prisms per season or, if all of them are converted in shards, 25 shards per season. Enough for all the masterworked armor one may ever need (since you morons decided to sunset armors, these are extremely valuable). So, you removed from us 25 “easy” shards per season to give us 3 for the whole season. That’s a bad joke. And you, Luke, are scamming people’s time.
Masterwork cores drop very frequently from many sources now - vendors, rank ups, deleting weapons / armour etc. Its not hard to get 10 quickly to convert to a prism. Prisms drop fairly regularly from Crucible when you have the mod on the ghost for precision kills. I generally get about 3 or 4 in a few hours session. Its easier than ever to obtain cores / prisms / shards. I started this season with no masterworked armour and only a few prisms and masterwork cores. I have never bothered at all masterworking to the top level any armour previously and never had a shard on my inventory. I now have every armour piece masterworked and 6 shards in the bank ready to go. That isnt through playing that much either - maybe 10 hrs per week. I dont really PvE apart from doing the bounties from the gunsmith each time im on and just crucible for the rest.
