First off, I've heard bad things about holy. But since healing frightens me, I've not tried it. Moving on.
Extra. Periods. Which. I. Use. To. Emphasize. A. Point. Which. I. May. Or. May. Not. Have.
I want sacred shield back. I liked sacred shield. It was an excellent button to press if I had no other buttons to press. And it turns out it was giving a significant bit of mitigation.
I'm actually enjoying ret. The holy power system adds some variation, some interest to it. It's mechanically fun. But it lost a lot of damage and even more self-healing. With divine storm no longer being spammed constantly thanks to t10 and no more instant flashes of light, my healing has pretty much vanished. Seal of insight helps, but it scales pretty slowly. I can use HP for HP, but that means no HP for DS to give HP and damage, so I'm having all sorts of HP problems with the HP system. Also, acronyms. Still, I like ret so far and I'm confident that some DPS tweaks can put it in a solid raid position. Also sprint judgement is pretty nice, though it could stand to be a little bit faster.
But prot. Prot prot prot. Prot. Prot. It has painfully slow HP generation, with only hammer of the righteous or crusader strike and they share a CD. It ends up feeling slow and clunky. Ret also has one ability to spam for HP, but it also has quite a few 40% procs for additional HP and they're on the common abilities, including the finisher moves. I like some of the ideas of it, such as picking between a damage finisher for aggro and a heal finisher which will bubble if it overheals. I like the reseting avenger's shield for something to change things up. I don't like being unable to get pursuit of justice at this level. I might have to switch my boot enchant to run speed, a clearly abominable act considering they currently have rockets on them. Replacing fine goblin engineering with... magic? Ugh. Even worse, magic done by someone else. How do I know if its unreliable?
What I think could help is adding a HP chance to AS. That would speed up the HP generation and make it so AS fees like more than just a misused interrupt. Also put the damage back on hand of taunt.
4.0 has all sorts of strange flaws which are bugging me. Sound effects randomly drop, while at times I can hear the sound of spellbooks being searched and bars being reshuffled. The new character display is great, but I don't like that it shifts my name over when I open the stats tab. Random gives no indication of how many justice points it gives, which incidentally isn't very many. The very worst thing: NPC names and health bars. Health bar display seems to be entirely random; just toggling it on and off will bring up new and exciting mixes of not all of the information that a player needs. Sometimes NPCs show their names above their heads even when not targeted, with the display option turned off. This creates a horrible appearance of all this smashed text floating over NPCs 50 yards away that cannot even be read. Actually that's one of the things that I loved about WoW compared to other MMOs: it didn't have stupid ugly immersion-breaking crap like that. It just looks awful. I'm sure it's just a bug as they sort out what seems to be a new feature, but it's not making the near post-patch experience much better.
It's not all bad though. I like reforging. I like the new way of organizing portals and teleports. I uh... wow, that was a short list.
P.S. Arcane is OP and frost is taking forever to kill anything.
