I've played my Shaman, Druid and Paladin so far and I'm liking the changes.
My Ret Paladin?
I'm missing Holy Wrath and the old Divine Storm. Yes, yes, we still have Divine Storm, but it requires 3 Holy Power. We have Hammer of the Righteous, but that requires a target -- I enjoyed being able to walk up to a group of mobs, press a button and everything near me dies. Now, I have to target something, make sure it is in front of me, and then hit Hammer of the Righteous.
I _love_ instant-cast Exorcism. Every now and then I'd bump the Exorcism key and I'd have to move to stop the casting (which screwed with swing timers), or I'd hit the key just as Art of War wore off. Now, I don't have to worry about it, AND, I have a good opener (it hurts, and hurts bad now. lol.)
I love the new swing animation they gave Templar's Verdict. Finally, my human female has a badass-looking swing, though it seems all races have a similar swing animation now. Still, though, awesome new animation.
Sacred Shield is an awesome little toy, 1k damage absorb per second (well, 5k every 5 seconds, you get the picture)? I'll take it. I'm not greedy.
Healing Light replacing Flash of Light, which is guaranteed Crit after killing blows? I'm healing myself for 45-48k after every KB. This makes solo MUCH easier. Also, it seems Word of Glory heals more too. I'm loving this part, I'm more survivable now. The class doesn't feel anywhere near as clunky or RNG-based now.
Then, I tested my Enhance Shaman...
Not too much to say here; my heal does a lot more and sometimes my spells cast twice (I healed myself for 75k with a crit+double proc once! that was hilarious), and she seems to be killing things a lot quicker (I pasted some hapless mob for a good 40k with a Stormstrike crit, and I'm wearing 377 crafted junk and using the brewfest tankards!).
I easily took out an elite mob who had 250k health like he was nothing (I easily healed through the damage with maelstrom-buffed heals). So, yay for enhance shamans being fun again, though I did notice there appear to be cooldown gaps where there's nothing to press for 1-2 seconds at a time, but meh. I can put up with that, no problem. I'm probably missing something.
Then, this morning, I tested out mom's lowbie druid, Lv70-74.
O-M-G, what did they do to Feral Druids!?
She was doing fairly well as it was, then this morning I took her out and leveled her and the first few fights I was like "holy sh.....".
Good thing she wasn't in the room with me, lol.
Let's see.... Predatory Swiftness now allows you to cast Healing Touch (which heals for more than my total health!!) without leaving cat form. I have Typhoon now, which I can cast while in cat form, and my cat form runs at 144% (that's almost as fast as a level 20 ground mount!) with the Feline Swiftness talent.
But the healing... omg the healing... at Level 70s, my Healing Touch heals for 12k... I only had 11,800 at the time. Now, at 74, I have 12,500 and it is healing for 12,800 or so. I chose the Renewal talent, but I think I'm going to get rid of it and get that Sacred Shield-like Talent instead (Cenarion's something rather); I don't need a 2min (I think?) 30% heal with that crap. I know Healing Touch will lose a lot of power, but even if it still heals at least 20k, that will still be quite nice.
Oh, and they seemed to have *seriously* buffed that HoT spell you first get too... it was healing me for 2-3k a tick at Level 70.
Can't wait to try my other classes!
