Some really good suggestions in there. Thanks for taking the time.
Interface/Options/Gameplay:

- Ability timer fix: Timers aren't holding their job together, an ability/spell should be ready, timer has already ran out, but when trying to use the ability or spell, you only get a message saying "Ability/Spell cannot be used now" ..so there's no way to tell when the ability is really ready.
Yes. For some reason, the countdown goes: "3 [pause] 2 [pause] 1 [pause] 0 [pause] [pause]" and then you can use it. Zero should mean there's no time left. And why is there an extra pause on zero?
- Multiple action bars.
Yes, please.
- The option to toggle action bars visibility on/off. Not just show them "when triggered" an ability.
Yes. It's annoying when I'm fighting multiple mobs, want to cast Cure on myself, and the mob dies, so the action bar is no longer up. I've got to find the 2nd mob, click on it, click on it again, and then I can cure myself.
- The item list response times are still slow, as to when swapping items from retainer to character etc.
Yes. There's about a 2 second period after you give an item to your retainer that you've got to wait before you can click on anything else.
- Erronenous clicking while trying to sell items. Even if I do click on a certain item, it will ghostly click on the item next below in list.
Wow. I thought this only happened to me.
Bazaar:

- Merge retainer bazaars or create an auction house that covers up all the worlds need. Everyone is residing in Uldah atm, and probably don't give a hoot about putting stuff on sale in other cities. It's too much of a trouble to browse all cities bazaar areas. Or if this is "too good" then at least make it so that the bazaar search would cover up all cities.
Yes. When I'm shopping for a new bow, I've got to travel to all 3 cities before figuring out that nobody is selling it. It would be nice to just travel to the city that has the bow in stock, or just know that no one is selling it at the moment.
- Overhaul of the bazaar search system. Make it more useful at least and add in the planned keyword search.
Keyword search would be great, rather than searching through a byzantine maze of menus for an item you want. For example, where would you find a Sunrise Tellin (an oyster/clam thing that you get from gathering and is used in making Sea Sand, Lightning Crystals, and a Conj wand). Answer -- the Tanner's Ward. Wha--? I would have no idea where to find those if I didn't look them up on 3rd party sites.

Here's another test. Let's say you're looking for Flax (a plant you get from gathering that's used to make Linen Bowstring, Linen Yarn, and Flaxseed Oil).

Well, the Grocer's Ward includes "Grains." But it's not there. The Chirurgeons Ward includes "Reagents" and "Oils." But it's not there. Tinkerer's Den has "Sundries." But it's not there.

Answer -- the Clothier's Ward.

So the menus and categories are not always intuitive, and it can be difficult to find things. And since there aren't complete lists of everything in those categories, if the item isn't being sold, you never know if you're actually looking in the right place.
- Fix the "hit a yellow mob, get less skill points" problem.
This drives me the most crazy when you're doing a leve where the mob flees. Since the run often takes more than 20 seconds, it disengages from combat, and you get less SP for killing that mob. This has to be a bug, right? Surely they didn't design the leve knowing you'd get nerfed SP.
- Having a battlecraft leve on 1 star or 2 stars or even 3 stars does make a difference on the gained SP. But having it on 4 and 5 stars are just a waste of time compared to the monster toughness they initiate. From what I've experienced, it's just better to keep leves at 3 star difficulty, higher difficulties are just a waste of time if you're still able to beat them, but the monsters take ages and ages to kill without any real significant extra SP gain compared to 3 star difficulty.
As I understand it, for every star you add, the mobs go up 5 levels.

The problem is that you don't get any benefit from killing a mob over 10 levels above you. So if the mob is 10 levels above you at 3 stars, there's really no reason to run it on 4 or 5 stars.

I'd add to your list -- There are currently NMs that aggro placed right in the middle of where you need to go for leves and behest. Alux is a pretty prominent example of this. Two night ago, while I was re-arranging my Macros to update my gear and abilities (/sigh), I ran two behests in Mun-Tuy. Both behests required you to fight mobs in the same room as Alux. Since I was soloing/duoing them at level 29, I got killed almost immediately after entering the room. And since the Battlewarden was in the room with Alux, I couldn't quit the behest. So I just died a few times, then waited at the crystal for 20 minutes to run out.

Then I ran my first leve. Which required running between different groups of mobs. Two of those groups were on either side of Alux's room. And every time I ran through the room, I got aggroed and killed.

Those leves and behests are basically broken because you placed an aggroing NM in the same room as them. Please move Alux somewhere else.
