Strange, I play it from time to time and have 285 Light without getting rewards from Raid (got flawless in Trials tho). There's no grinding in this game, I already have almost full collection of weapons in my Vault lol. Compared to D1 "grinding" here is a joke with clan rewards and easy weekly activities.
Maybe I should clarify. I am at 289 light and I feel like the progression is really slow unless the light level is meh and doesn't mean too much when it comes to progression itself. It's just once you hit a certain point its like your playing the game but nothing is happening.
Normally this is where I would play the PvP but I'm not really a fan.
