1) Whoever was going off about how shamans suck because of this that and the other thing... WTF are you looking for, a class that can MT, chain CH, and provide full debuffs? I've played a shaman since I started on SOD well over 2 years ago. And they fucking own.
-Slows: IDK whether shammies have the best pre-archaic slows. What I do know is that we have no problem slowing mobs quickly and effectively, either individually or in packs.
-Malo: Owns. The casting time is kinda long, and the mana cost is kinda high. It takes, what, like... 3x Canni IV to make it up, all other mana regen aside? SAY IT AIN'T SO! If you have decent charisma, you wont' even need to malo. I get fewer than 1 slow in 5 resisted, except on particular mobs where I know to take precautions. Fewer still of my dots get resisted, again, with particular exceptions. In those cases, even malo probably won't help much, so you just pick some other means of DPSing.
-Mana Regen: I've kept a warrior and a rogue alive while 3-manning (well ok, 4-manning, I didn't keep the wizard alive when he got aggro after the first nuke) the Great Nazdrich, who hits for a little under 1k a pop and rampages. This was while slowing DoTing. The mob has probably 75-100khp. And I wound up with over 40% mana left over. Shaman mana regen is unbelievably nice. I have never gone OOM while just healing. Ever. I occasionally do while DPSing and keeping plaguewind + relic DoT on 3 or 4 mobs at a time while backup healing, but you can be 100% sure that if a decently played shaman goes OOM, it means the other casters in the group ran dry long since.
-DoTs: Whoever said 2-3k/tick is either full of it, or else spending 100% of their time casting and recasting DoTs (assuming a single target). But a shaman can easily put out 200dps on a single mob, and far more than that on a larger pull. Relic DoT alone does over 130dps, a buffed pet will do over 20, and slap on a disease dot and you've got another 50 easy.
-Buffs: You're right. Shaman buffs DO own.
2) Kirin: You need to get into some better groups. I have to struggle to free up buff slots.
1. JB
2. Aego
3. focus/won
4. EoT
5. EoTW
6. Regen
7. Haste
8. Illusion: plate
9. Damage Shield
10. BP clicky
11. Pink heart/cotp
12. Magic Resist
13. HoT slot
Others: Movement buff for outdoors, Seasons, BST crack, RBOW or pally/rng innate combat proc, Niklothar, and invis to name a few. That doesn't include the need to leave a slot or two open for debuffs so your buffs don't start getting overwritten. Or for combat procs on your weapons or armor. And ALL of that except the DS is covered by just paladin, shaman and chanter. And if the shammy doesn't have relics, you may also need see invis and/or EB in there somewhere.
It's very, VERY easy to fill up all your buff slots. It has nothing to do with greed, it has to do with having a hell of a lot of extremely useful buffs and not enough slots for all of them.
