The ability to just walk into a dungeon and join in on the combat without organized, formal groups. I'd heard somewhere previously that loot was individual due to the "anyone can use anything" theme they'd wanted to keep from other Elder Scrolls games, and that if you'd participated in combat, you get loot off the creatures killed.
Not sure how that would work with instanced dungeons, but I'd still like to see it. I'd also like to see that happen to raid content. There is no reason we need yet another game that requires one to join an organized group to kill dragons and organize dungeon crawls.
No strong influence on formal guilds as they tend to be in other games. If the rumor of being able to join multiple guilds is true, then there is no reason to focus on them, when that defeats the point of them.
No crafting components that require a raid group to obtain.
Slower leveling. More focus on the journey, not the destination. We don't need another game exclusively focused on the endgame. With how Cyrodiil's PvP scales your character, this should be completely possible to do. Don't need to rush to endgame when you have half a shot at PvP at lower levels.
Skill > gear in any and all circumstances. If I want to participate in a boss battle naked, if I'm good enough, I should be able to. There should never be the ability to outgear content.
Don't get me wrong. I have no problems making friends. I have plenty of them. I just have no desire to join a guild full of people I probably won't like(most of my friends do not pursue more difficult content) just to do content more appropriate to my skill set. I should be able to jump in and kill things. I have no desire to play a class I dislike just so I have a shot at getting in pickup groups. I see people, I should be able to help kill what they're killing without the formalities of grouping.
It sound rude, but I do not:
Have a desire to form formal relationships with everyone in game to get something accomplished
Want yet another game focused exclusively on endgame, where everything is rushed through and then full of whines that there's nothing to do
Want to have no other choice but to hang out with people I don't like on a regular basis to do what I want to do in the game.
I'd be in favor of having any and all instanced content scaled like Cyrodill is supposedly, so that it doesn't matter what your gear/level is, you're all on mostly equal footing. You want bragging rights, go PvP with the leaderboards.
I'll probably get flamed for this but eh. I grow weary of games that essentially force you to rely on a static group to get anything done. I'm a freelancer. I prefer to keep it that way.
