TLDR =
1. Ware a Shield... it DOUBLES your Survivability at the cost of -10 to 12% DPS. +25% Effective Standing HP, +25% Healing Effects, +40-50% Spirt Regen.
2. Ware Stam/Sprit Gear (with some int)... It increases your Kill Times by Reducing Your Down Time (best DPS Gear for Shaman basically)
3. Use 0/X/21 Talents! With your First 21 Talents in the RESTO Tree. It makes you another 100% harder to Kill and has Melee / Spell Hit (big deal for killing runners).
4. The Above 3 have a POWERFUL Positive Feedback loop. Aka you have more HP so you can Spirt Regen in combat longer for more mana, which gives you more healing, healing that is more effective do to more armor... giving you more time to damage and kill mobs and regen and heal... oh look? is my mana pot back up again already? Have I been fighting 4 mobs for 2m already? Huh... I didn't notice...
5. Have an ESCAPE PLAN... Specifically = Earth Bind Totem + Target Dummy + Free Action Potion + Nifty Stop Watch + Natures Swiftness...
Held in Reserve to Get your but out of the fire. (Note: NS is Critical here... as Ranged Casters and attacks often don't care about Target Dummy... and when you RUN it will likely be with you at 50% life or less... which a couple fireball crits to the back can easily take out... NS Heal laughs at this. Other way you can die is surviving the mobs you are running from with 10% life... only to not have enough HP to HEAL before the 1 mob you pulled running away kills you (your Spell Pushback can fail even at 70% Chance). NS fixes this. NS can also be used OFFENSIVELY sense it has no GCD to kill Runners if Earth Shock or Frost Shock MISS / RESIST... care with that though)
6. Have a SMALL LIST OF RULES CUSTOMIZED FOR YOUR DUMB BUTT specifically, based on your own personal lessoned learned... to follow religiously while Leveling. My paladin list has 7 Things for example... ALL of them learned from previous Deaths.
7. SSF in at the end of the video.
8. Watch Calamities mob LEASHING Guide. 10m Vid... need to know how to run from mobs.
