I wanted to list the stuff I like and the stuff I am disappointed in 5.2. Let's see what people are happy about and not so happy about!
This is just a start, I will likely update as time goes on:
Pros:
Rogue dps! Feels like I mowing mobs down in PvE, haven't tried pvp.
New areas to explore, I love the feel and the graphics (Well done Blizzard!)
Faction tagging rares
More random rewards (coins, rep ensignias, etc.)
New one person scenario for gold and rewards
Cons:
They didn't implement the engineering items...not happy bob, not happy...
Upgrade vendor is gone (hate it when they remove content)
Butt-ton-more-dailies for little reward
Heirlooms are too expensive (at least 25-50% too much) Old staff plus 3500 JPs? Really? Why?
Can't just portal to Isle...Why do I need to travel to a portal that could have been set up in the Veil?
