PvPing on my ele sham.
It's MUCH more fast-paced than before. I don't have to wait for my Elemental Mastery to come off CD to enjoy my insta-blast Lava Burst since the surge procs turn it insta-cast. And Astral Shift is such a godsend, omfg. Frost Shock talent'd into a hard CC is super nice, too.
I think it's a bit clunky having to have a bunch of totems all piled up and only being able to put out one at a time, though.
watching hpal pvp videos.
wtff holy shock.
and murder of crows is like omfgbirds on my screen.
Shadow spec as of now for questing, will go disc for dungeons.
@Joel here are my add ons, my UI is custom and made with TitanPanel and Bartender 4. But I'll include everything else.
AtlasLoot - Looking at loot tables is handy
NPCScan - Helpful for hunting rare NPCs for achievements (Northrend+Outlands) and for looking for rare hunter pets
NPCScan Overlay - Colors areas where rare spawns patrol
Shadowed Unit Frames - My player frames, smaller prettier and more compact that default
Archy - Archaeology Assistant, makes it much easier
AuctionLite - It will auto-input the price for your item to make it sell the best, makes mass auctioning easier as you don't have to look up the price for each item
Bagnon - SUPER HELPFUL
Bartender 4 - Complete customization of action bars, very easy to keybind
Chatter - Chat add-on, it recognizes links and will copy them to your clip board (my guild posts shit all the time), and makes the box smaller/neater
Clique - Can make click-bounds for all spells (helpful for healers) and they work on any unit frame, ie the default frames or Grid
DBM - 'Nuff said
Decursive - Easy debuff removing
Grid - Customizable unit frames
Parrot - Combat text, helpful for certain class mechanics (fire mage filtering out shitty crits)
Postal - Mail box add on, allows an open all feature. Great if you auction everything with an auction add on
Quartz - Cast bar, more detailed than default
RSA - Yells out when you cast important stuff so other people know not to do something similar
SexyMap - Because why not?
Skada - The everything meter
Tidy Plates - Default ones suck
ThreatPlates - Great if you tank, change colors based on your aggro, easy to tell if you lose aggro
TitanPanel - Small bars at top and/or bottom of screen containing loads of info, makes your UI look more put together and it basically replaces everything the default has to offer
I manage all my add-ons with Curse client (some I didn't list as they're more specialized), instead of hunting down the file and copying it from Curse.com into your WoW folder, I'd rather have the extra program that puts everything in the folder automatically and it's super easy to update add-ons as well.
