Hey,
I played the last BWE and enjoyed it quite a bit, but there were some things that I think could be tweaked a bit. Some of these are taken from earlier posts, so credit goes to whomever it came from.
Grapichal
-Add some more graphics for ranged attacks, constantly seeing different colored balls flying from char to char gets repetitive (this is for staff/wand type weapons)
-Beef up visual impact of some spells, make it so that their effects are more apparent in-game and more impressive (ex. the "ice spikes" spell looks like small lightning radiating out from target, if instead something like icicles bursting up from the ground/falling from the sky to hit them and surrounding area)
-Add armor options, for more covering or more/less ornate; also, an ability to add textures/patterns to armor (ie. could add flowers/birds/celtic knots to cloth, or scroll-work to metallic armor)
-Add blood as an option, to show when damage is made, when someone is bleeding, etc.
-(re?) Add the ability to have long hair, and facial hair, maybe allow them to be changed later by going to a barber/hair-dresser
-Add more options for dye: allow coloring main portion of armor, utilize a rgb mixing style with other colors (ie. gold) being more rare, allow previewing dyes
-Add proportions to character creation, allow making rotund/skinny chars
-Allow toggling display client-side of certain effects/items, such as capes and things like the new rank thing
-Mark members of your party when in town, I think a red crossed sword thing above their head would be pretty cool
Emotes/Chat
-Allow "targeted" emotes, where the currently selected character (or npc) is the recipient of the emote ("Thrall points at Fluffy" type thing)
-Add some sound emotes where your character says something ("/hi" would have your char say aloud "hello" or something like that)
-Maybe add some toned down emotes, as some may find the dances of some such as the female elem. a little offensive (I don't personally, but...), and move the sexy dance to something like "/sexy"
-Have the chat filters save state, so that I don't have to uncheck emotes every time I play
Quests/Map
-Mark quests for difficulty, red=nearly impossible, yellow=difficult, green=easy, it could be determined by your level and average level of current party, maybe
-Allow accepted quests to be removed from your list, maybe then allowing you to pick it back up by going back to the quest-giver in case you drop the wrong one on accident
-Maybe add the ability to put notes down on the in-game map, and make mousing-over things on the mini-map gives some basic info on the character (name, purpose [ie crafter], level, etc)
World at War
Personally I didn't participate in this but I have heard some complaints about racism/nationalism due to the national aspect.
-Maybe you could make countries from in-game countries and randomly assign them to guilds and characters when created, and joining a guild of another country would switch the char to the guilds country. That way you would get people from different countries in the same in-game country. Then the countries member guilds could be randomly shuffled (as in who is sent where) every couple of months in order to balance for guild growth/loss. Again I didn't play, so I don't know if this was really a problem.
-As a previous post said the WaW tourney should be held once a month, then the members of the winning country gets the content for the month, until the next tourney (or couple weeks/whatever)
Misc
-Control over your pet/hench's state of mind, like aggressive/defensive/passive
-have enemies lose aggro sooner, I ran clear across a county in pre-sear trailing 20+ enemies and never lost one that I could tell
-a ready button for group members to enter an instance
-more customization for controls, ie. map keys/change mouse sensitivity
-more ambient sounds, footsteps for your character and things like clacking stone/rumble for stone elementals, etc.
-more info about characters when selecting them before entering game (level, classes, location)
-the party dialog needs to remember where it was when entering town, in instance it always went back to where I had set it, but in town it moved to its default(?) position, covering up my exp. bar which I had put above the mini-map
-JUMPING! you should be able to jump in-map, it would allow more maneuverability in-game, and should have no effect on combat (attacks would have same chance to hit, so people don't just jump everywhere, like crack-rabbits

); or re-work the maps to remove some of the "invisible walls" that occur on slopes/random places
Lastly, I know that ANet is aware of the desire for alternate platforms for this game but, Please, for the love of all that is good,
release a Linux client! I will be buying the game when it is released next week regardless, but the decision to buy add-ons would be greatly influenced by whether there was a Linux client; as dual-booting is a less than elegant solution, and the $15-a-month fee for codega is not something I want to do.
Thank you for such a great game, I'm looking forward to playing it much more in the future (on my Linux partion, I hope

), and I hope that my suggestions help make it even better.
-geez, this got long-
~Edit~ improved readability
~Edit2~ Add idle animations to NPCs, most importantly the ones in instances, but also in-town, so that they aren't just standing there waiting for someone to talk to them; have them making something, or twiddling(sp?) their thumbs or something, until they're spoken to
