my wish list woul be
1. more double attack
Always good, we aren't at cap anyways

2. a new dps disc or our old one upgraded if upgraded plzzzzzzzz target pet ).
We don't want it to target our pet, we lose DPS!!!

3. both our pet shielding aa upped in mitigation and damage reduction, the mobs in these new expansion hit just to hard and often.
There's lots of things to fix this problem. Just need a developer to address it. This is a start though.
4. pet dps upgraded in line with the new expansion especially its proc line it has just fallen to far behind.
This is a "triple edges sword" honestly

They up our warder, we loose DPS. They up our DPS, it leaves the warder stagnant

And reguardless if what they do, Mages will cry

I could see the pet proc damage getting a nice 40% boost though

5.i would like to see some sort of bst summoned armor or weapon for our pet with stats that would be cool but i bet mages would /cry lol i hate begging for all that gear or buying it.
It would be nice, but Mages would cry (and doesn't really fit the monk/shaman theme). But it would give us more reason to use Conjuration. Mabye a vendor in GH who sells summoned items?
6. as mentioned befour our pet heal proc up the healing on it or make a aa to up that and drop the charges.
Remove the charges, its all random anyways.
7. oh yea what about a few more seconds on our defencive disc 3-4 would that really hurt
Messing with our defensive is like talking about a religouse topic, its sacred to the community.
*** Note ***
I have lost all love for the Mage community

Individual mages are awsome, but as a community they have held back too many classes. I guess it also speaks volumes to their ability to address their concerns to the developers better than any other class. Although, they did get shafted in HoT compared to the last few expansions.
I also wish our defensive Disc wasn't held to be so sacred, but I have learned to live with it.
We had some nice improvements with HoT and finally found a niche as a utility class because they refused to set us up as a DPS class. As long as they are going to keep giving us utility, I see no reason to stop asking for more utility.
