I have not noticed shards any harder or easier to get since this hotfix, you mention. You are guaranteed at least 2 energy or shards everyday from running the daily heroic on lvl 28. You still have a chance at getting from getting gold on public events. You still have a large chance to get 1 shard or energy for just completing one public event a day. Lvl 24 strikes now have a chance of giving you legendaries/exotics as rewards which can be broken up into materials. So do tell me how you are anymore limited than you were 2 weeks ago.
