Can consider:
-Special Titles / logo beside name to represent certain accomplishment ingame as a bragging right. Ex. Clear challenging / heroic missions 100 times or 1000 pvp kills
- exotic parts / recipe should not be guaranteed drops, it should be low chance so that players have content to grind for and things to look forward to.
- bring back gear/weapon recipes with up to date gearscore. Players can grind for gears to dismantle or grind for materials to craft the perfect weapon or gear stats.
- make more skills viable and stronger, so people are more motivated to grind for skill power stats and sets rather than just pure damage set with weapons.
- Exotic mods
- Cosmetics
- Faction rep with the settlements for access to better stuff, and eventually maybe settlement-unique exotics and cosmetics
- An upgradeable personal space at the White House, that you can display stuff in, and unlock decorations or whatever for, by accomplishing things in game.
Decent gear-sets without gimmicks which are incredibly content specific, more exotics and vanity items - all the good stuff which we already have, and will be coming no doubt. I have a lot of faith that Div2 will surpass Div1 in every way.
One of the most unique things I've thought of was when I was clearing out the Hunters; I love those guys. Their spawn animation, the smoke screen effect, is awesome. I'd love it if you could get unique spawn-in effects like that. So for example, as a part of completing the 12 Hunters in the game, one of the rewards was a unique fast-travel spawn animation similar to that of the Hunters which you could equip like a vanity item. I thought that'd be cool.
Its not the loot...its the re-playable content to get the loot. Once they put all the new gear into the single raid or DZ...there goes Check points, loot boxes, the open world exploration, elite patrols, Territory Controls, Missions, supply drops, Bounties etc etc etc...98% of the games main playable content will become useless and no need to play to grind for gear. All you will do is log in run the DZ till your sick of being ganked or run the raid 2-3 times a day at 2--3 hours a run (if you finish it and get that one piece of gear you may have been looking for thx rng).
I am solidly deciding 500 is end game gear for me. I love playing on the huge awesome map.But I cant stand the thought of being stuck in the DZ for hours on end daily or the same raid zone over and over for the next 5 months just for a slight chance at one decent 515 gear piece...just think about that and you will see that grinding for loot in that kind of contstrained/limited playable content is not what this game should be about.
