I'm sorry, but there are plenty of people that have multiple hours in PvP, and have attempted the lighthouse more times than me and you, and just can't get good at it. I don't believe everyone can get better. No matter how good I get, on good days I average a 1.8 probably. I highly doubt I'll ever average over a 2.0 in any playlist. And I've been playing FPS since Goldeneye. Why don't I have a high Grimoire? Because I don't care about it. Same reason I've never done the Oryx raid, or beat Skolas. Or even Crota on Hard. Could I do those things in a weekend, or even a day? Sure. Yeah. But YouTube and ghost hunting entertains me about as much as raiding does anymore.
