A few things that can really turn this game around quick:
*I'm ok with static rolls but the one thing that can flip this game upside down is the mod system. The potential there is unlimited. Hardcore players could have something to seriously grind for if done right.
*We need specific loot for activities such as strikes, sectors, adventures etc...We need an incentive to do them which currently just isn't there at all right now.
*Exotics that truly feel exotic. The game is missing guns that feel like they have the potential to be iconic. In D1 we had infamous guns like Gjallarhorn, Ice Breaker, Thorn, Hawkmoon, also Vex Mythoclast and Suros in the beginning. Were they OP they sure as fuck were but for a good 6 months we got to tear shit up with them before they got nerfed. That was fun. We all remember those guns. Nobody is going to look back on D2 and be like "hey that game sure was balanced", but you'll damn sure look back on D1 and the few guns I named and be like those were memorable times.
*Raid gear: imo needs to have raid specific perks attached to the gear. Right now theres nothing special about the weapons armor. There needs to be something that also separates prestige gear from normal gear and no a fucking shader doesn't count.
*PvP: ya 4v4 is a really good model for the competitive scene. However not everyone is MLGyoloswag420noscoper. Bring back 6v6 for quickplay. Let us pick which game modes we want to play weather it's clash, control, supremacy. Bring back rift and mayhem. Give us more options so shit doesn't get stale.
