Not sure parts of that were in English but here's Enhancement 101.
Standard Totems: Strength of Earth, Windfury, Magma, <random water totem>.
Priorities
Lightning Bolt at MW5
Lightning Shield if empty
Magma Totem if expired
Stormstrike
Flame Shock if not already ticking
Earth Shock if flame shock is ticking
Lava Lash
Fire Nova
Doggies and Shamanistic Rage as appropriate really, in a 3 minute fight use them at the best time, in a longer fight use them immediately, refresh lightning shield or magma totem if there's a free GCD somewhere (LOL). Fire elemental is handy for getting more GCDs as you don't need to refresh it every 15 seconds.
Addons
Shock and Awe - The best shaman addon out there
Totem Timers - My preferred totem management addon, others like YATA
Slow weapons in both hands, fast weapons are disastrous for enhancement DPS. Windfury on the main hand, flametongue on the offhand.
Spell hit needs to be capped, that's 420 for a spacegoat. Hit above that level is less useful as it only affects white damage, it's not completely useless but almost anything else will be better.
Gems should be 40 AP at low gear or 20 haste at high gear, enhsim needed to tell you which you're at (ShockandAwe has a character export function for enhsim as it's written by the same guy).
Always recall totems when the fight is over, accidentally pulling a pat with totems while the healer drinks means you fail at shaman. Forgetting to use cleansing totem and tremor totem where appropriate is also fail.
My lightning bolt button is a macro with Alt triggering a healing wave instead, useful for oh crap moments and means both MW5 abilities are on the same button/keybind.
