Tiered/learning curve! Base power on all gear then modified with activity mods to increase power further! I.e power level 360 across the board, Heroic strikes drop 360 and 355 in sandbox. Prestige nightfall drops mods to 370 and base entrance to raid drops mods for 370 also, finally prestige raid takes you to cap! Curve, grind and varying level entrances to activities easing you in but also levelling you up, constant grind with constant progression, rewarding time spent across the board and making no need for stupid pre party requisite and time walls!
