Well lately in raids I have had trouble surviving in raids, from the trash mobs. Whether it is the saw blades from the saw machines from void reaver trash, or the trash mobs in SSC, or basically any trash that has aoe. I just cannot seem to survive at all.
And then there is the getting one shotted by the maulgars in gruuls lair. I wish the mage class has some sort of survivability. This is why I use my stamina gear when we clear trash mobs, just so I can survive.
Even on boss fights, we make the healers struggle because we usually get one shotted or two shotted before were dead. For example static charges when were fighting vashj. If I dont get an immediate heal I am usually dead. The posoin goo at the end, if I get hit by two at before I get a heal I am usually dead.
I know that were supposed to be squishy, but damn blizzard, give us a little more hp so we have better survivablity. Because any alive class is > a dead mage.
