Well as a Casual player myself (I have to work to pay for living), what is desired is not easymode, but variety in game play. There neeeds to be options of things to do.
From what I am hearing here is that there is currently no variety in end game and people are bored. Bring on the Nexus!
Someone mentioned earlier about too many casuals playing MMOs and that has a bit to do with what I have to say about this.
In reality, there really isn't all that much wrong with the game from what I can tell - it's the players. Lately, on pretty much any MMO I've played be it RuneScape, WoW, Rift, Tera, etc, they're all the same. The players on the game don't want to do any kind of leveling, any amount of enchanting that takes more than a few hours to a few days to get the best gear. They just want to jump in and go straight to PvP and that's the extent of their interest in the game. Nobody has any patience anymore, which is why everyone uses bots on games any chance they get. I don't feel like playing a game solely for PvP is wrong or anything, but going in to a game wanting to do nothing but pvp and be the absolute best is what's ruining the experience.
I've never been in to quests myself but it seems that the majority of these games make quests for a reason. You're supposed to take your time leveling, doing the quests, exploring the lore, etc. None of that really interests me and so I haven't actually played MMOs in a while. It isn't the game developers fault for making a game that caters towards casual gamers when a small percent of people that rant on the forums are playing it solely for PvP. It isn't their fault that those players who are ranting played the game 10+ hours a day and did nothing but blow thru the quests and reach "end game" ONE month after the game's launch. Playing any normal amount of hours would leave you like level 30-40 or something, and new content would have been released and by the time you were high enough to play it you wouldn't be complain about no new content.
IDK, I haven't played Tera, but I think this applies to most games and it makes sense why people are so upset with how things are going here.
Casual players with full time jobs and social obligations won't have the time, even if they have the will, to make it through the endgame time sinks. RNG based gear progression means that players with limited play time could go days, weeks, or even months without advancing their characters.
Most players, along with myself, who are already 60 are the type of players that will tolerate the randomness of gear progression. Some may even like it. The issue is, if the core and casual gamers all quit, then there won't be a game to play anymore.
The part where you said you haven't played the game everyone in this thread is talking about kinda detracts from everything else you said entirely.
