@ Everyone:

Dont expect u get this 2200 too. Beside the expierience and skill in arena you need perfect settings/macros to compensate your lack on free movement.
You need a healer who back you up 100% all the time even when you take heavy burstdamage, so you are able to drive full damage and dont waste time with healing yourself.

S3 Multiboxers are beatable easily by S1-Teams, if the opponent is skilled enough they will heavy abuse LOS. I met Teams on 1500 Rating who anoys me 30 minutes long with LOS, short CLOS-Attacks every minute, killed very careful my totems with Rang1-Spells followed by Painsupression-Priest-Fearbomb + Warlock-fear +Warrior-Fear. If they assume a own little mistake, they did a fallback.
There exist several tactics to beat us. Manafights, heavy CC etc.

In lower ratings you will face Teams which arent made for higher ratings, like Rogue, Rogue, Mage, Mage, Priest or Hunter, Warlock, Rogue, Druid, Priest. These teams can be very painful for you.
If all teams would know, how delicate Multiboxer-Shaman are for LOS we would never hit the 1500.
