Yeah it is which is why the world's should be explored with up to six guardians and there should be playlists to accommodate 1 - 6 player fireteams not this either go in solo. Or with 3 no if I go in solo it should be challenging but doable. Think monster levels in Diablo 3. Also you should have made the old tower a raid with Siva taking over and using everything in our old vaults against us. And make that the only way to get old d1 weapons find 3 relics from last word to recreate it. Or 3 relics from ghall but make the drop rates low so we can farm make the raid fun so we want to farm. Change mechanics use different bosses with Siva bassed around old armour perks or weapon perks that work against us.
