Bad habits and exploits arent going to change with the new META. People have found outliers in every group of weapons from every dlc that outperform other guns in a given situation. Example: Crucible Vanilla Destiny- Suros Regime dominated Patch with TDB- Rise of Thorn and TLW HoW- Hopscotch Pilgrim and Messenger So even if our old weapons dissolve to dust, there will be new outliers that fill thosr voids. There will be some OP guns and unless you have other OP guns to counteract those, then its the story of now all over again. My 2 cents anyways.
