Your power comes from your build, weapons and abilities Would be even more stupid if we could start one shoting older bosses like world of warcraft

Since seasonal content become a thing. We in 2,5 times powerful then we were when Last Wish raid been launched (600 light was cap for optimal Forsaken dlc). So today we suppose to melt our old enemy's, but we don't. Because new players already 1350 when they appear in game and you can hit hard cap level in two weeks at most. Bungie could make new guardians appear with power level at 1. But in that situation they need content that will let people slowly gain their power. They don't have content, because of seasonal model everything expect main DLC materials will be annihilated when new DLC appear. Meaning Bungie short at time and can't let new players to slowly progress through story and lore. They need that new players jumped on train while it's moving in incredible speed (FOMO) and could catch up with any activity in two weeks at most (that's why Trials and GM appears on month later after season starts). And since we know that Destiny is short on content, Bungie can't give us power that we have, if they do, then only new content that have high light restrictions can be a problems. Everything else will be feels like go on patrol. Those who played in Destiny long time remember when season of Forge started and first forge had 615-625 enemy's, whole community staggle to compete forge at all. Most players could compete only two waves at best. That's what being underleveled means.
