A friend and I were talking the other night. About how every face to face melee fighting class, can wear Plate cept for Shaman. Warriors fight face to face and can wear plate. Druids can fight face to face and Shapeshift to boost armor and def. to equal mail and plate with good gear. Pallys fight face to face and from a distance as healers.
But Shaman fight face to face and must wear mail... My friend and I thought it seemed off, on Blizzard's part. Seems like Shaman should have plate. Since we also can fight face to face and from a distance like Pallys and druids.
I don't seem to be having the problems in OL that you are. I own most everything no more then a few lvls above me. I usually pull groups of 60s (2 to 3) just for fun. While playing a good grinding playlist and ripping into them. I am LvL 62 Enhancement Shaman. Currently some of my base stats are, AGI +140, Stam. +115, and Armor 3269. I have been in OL since 58. Mostly in Hellfire Penn. and outside Shattrath City.
Are you using your Stoneclaw totem? When ever I have a add or two. I just drop it, and say "Here watch the stick." While I bash the first mob. I also have gear for survivabilty and Crit. So mostly +Agi, +Stamina, and 3 peices of the PvP 60 Epics(For the awsome well rounded stats, and enhancement to shock spells.)Not to interested in the full set, seems like it would be gimp without other OL gear. Then DW with two maces, just because those two OL green maces have high DPS mininum numbers, and +Agi, and +STR. I usally white and yellow crit around 1k adding up to around 3k about every other pull with WF. My two-hander is a OL green too, and can one hit 58 Orc casters. Making the ladies go "Ohhhh, Ahhhhh!"
I would look into all gear options and enchantments to help live longer. More health, or strength. What ever your build needs. Thoe, I like a strong mix of killing and living stats. Since no one ever won a fight by dieing. A good defence is often a strong offence. Like maybe that last bit of MP, would be better spent damaging, instead of trying to delay death.
Some mobs run at a certain point. Stoneclaw, distracts unwanted attackers. Expect to be hit, so brace yourself. Earthbind and frostshock can be used to kite, for a bandage. Never stop paying close attention to your surroundings. Finally, know your limits. If your HP bar is draining far faster then theirs. The battle most likely is lost.
Good thing, you have to kill a Shaman.... Twice. ;)
