Change, Remove, Add.

[StriderShinryu]

Change: WM on Bard to be something that doesn't make the entire class play different after it gets it to how the class played for the 50+ levels before it.

Remove: Crafting being nearly required to do so many things, especially given that to be even slightly proficient at crafting you have to level multiple disciplines far beyond what you might ever want to.

Add: A full and proper cosmetic system akin to what can be found in Lord of the Rings online with an always accessible cosmetic wardrobe that stores glamour versions of items. (Or, in a really big stretch, find some way to replace the current gear system with something akin to the one in Secret World where cosmetic appearance gear and stat providing gear are completely separate). The current glamour system is far too reliant on crafting, is clunky in execution and can be a real inventory space hog.

[Colorful]

Change: Make the entire world open with no loading screens, excludes cross continent travel and instances. Making use of airships/boats and the like for traveling over over or flying to the skies (think on the level of this. Obviously never going to happen as it's incredibly demanding and the game is on consoles and needs to be to maintain a sizeable player base, but hey I can dream.

Remove: Specialist recipes.

Add: Ingame parser only available in Extreme Primals and Savage raids.

I think Diadem was made for you definitely! ^^;
Please try to associate Diadem with Dynamis.
If a Diadem Hard mode only can entered by 3air-ships exclusively, and add weekly lockout, then it will be Dynamis in ARR?

[Bloodb]

Change: Lords of Verminion to be data-center wide.

Remove: Only being able to have 3 specialists. By buying another crafter soul with red scrips you can get a 4th and 5th and so on.

Add: A "Exclude armory Items" tab or checkbox when turning in Diadem gear.

[WellFooled]

Change: Monster strength/mechanics to pose more of a challenge.

Both inside and outside dungeons there is very little danger. In dungeons this results in many tanks pulling huge groups of monsters while dps/healers AoE them down pressing a single button. That is not an adventure.

Remove: The Goblet's "Housing Enthusiast" npc

That weirdo stands by the market board all day fanning himself while fawning over our houses. I've reported him to the Immortal Flames, but apparently being a creeper "isn't a crime".

Bah.

Add: More interesting Stats.

The stats we have now are amazingly boring, to the point where I rarely even think about them and the problem is compounded by the fact we have no other means of customizing our gameplay The addition of more interesting stats would allow for meaningful choices that differentiate our gameplay from other players, it would be a great starting point for more horizontal gear progression, and give gear meaning again outside of glamour.
