Hey, welcome back! I'm in a similar boat. Stuff you need to know: - New subclasses! Each class now has one subclass of each damage type. - Level cap raised to 40. Light from gear no longer raises your level, but instead is an average rating of your gear's armor and damage rating. Mission recommendations are based on Light rather than level. Don't worry though, you'll be automatically leveled up to what ever was the maximum light level your old gear would have brought you to. - Class items matter now. They have armor ratings (and therefore contribute to your Light rating) and have Strength, Intellect, and Discipline bonuses, as well as perks you unlock with experiences. - Ghost Shells can be found as loot drops, and also have armor ratings, perks, and stat boosts. - New equipment type called Relics, which also have armor, perks, and stat boosts. - If you missed House of Wolves, you may not be aware of a new Special weapon type: Sidearms. Semi-automatic pistols that go in the secondary weapon slot, very high rate of fire, decent size magazine (around 15 seems to be the average) and stability medium to low range, but very low impact. Opinions vary on how good they are, personally I find their high RoF great for ripping through shields and they can save you when you get an opponent down to low health and have to reload, just switch to your sidearm and empty it on them. - New Heavy weapon type, swords. Think Sword of Crota, but with ammo. - The gear grind is starting all over again. Your old purples and yellows are going to be useful in the beginning missions of the Taken King story, but you'll quickly find most of it outclassed by new greens and blues. Select Exotic items from year 1 can be upgraded to year 2 standards, for a hefty cost in Legendary Marks. Speaking of which, - Crucible Marks and Vanguard Marks have been combined into a single resource, Legendary Marks. You can earn all your Marks each week off just PvE or just PvP if you like. - The Gunsmith has a purpose now. On Wednesdays he sells field test items, which you can buy and score kills with in a particular manner (like "kill X hive" or "get X precision kills") to earn Gunsmith reputation. You get packages from increasing Gunsmith Rank, which can include cool stuff. At rank 5 he gives you a quest for a new Exotic hand cannon. - Most exotics can be earned through quests now, you don't have to rely solely on RNG. - There's a cash shop now. Currently the only thing you can buy is different emotes, but there's been a big brouhaha lately about micro transactions and slippery slopes. Don't let the chicken littles scare you, it's probably going to be fine. - Various buffs, nerfs, and balance fixes you probably missed. I'm still trying to figure them out myself, but hand cannons have noticeably shorter range and worse accuracy, shotguns don't have the Shot Package perk any more, Auto Rifles are a bit stronger and more stable, Recovery is a bit faster at the low end and a bit slower at the high end. Some other adjustments to specific subclass abilities. I'm probably missing a few things, and some of it I'm still figuring out myself, but I hope that helps get you back into the swing of things. Let me know if you have any more specific questions.

May the cones guide you to victory!

Do you have red death? If so, glad to see you. If not, don't bother. It's as bad as thorn was
