Grind is always meaningless.... now serious, what do you expect? To achieve some everlasting advantage? That because you played since year 1 you'll always have the upper hand for the next 10 years? Tiered progression games need reset points for new players to come in and to equalize power differences that build up over time, simple as that. Destiny may not be an MMO, but gear and the power associated with it, works much like it was one. When a new expansion hits, everyone want to play the new content and have a challenging (but not impossible) fresh experience. That means you have to bring new players, try-hard veterans, and year one casual players to roughly the same power level. Want an MMO where you keep your advantage, where grind isn't meaningless? Try real-life..
