Parenthetically are written 2.2.3 patch damage.
"3 AB -> AM -> fireblast"(c)Quantz means: you cast 3 AB, getting debuffed to 1.5 sec cast, -> 5 sec AM -> 1.5 sec FB -> 1.5 sec AB, 8 sec passed, so the debuff wears off, and you lose no mana, while casting 1.5 sec AB. In the middle of the fight:
1.5(AB)+2.2(AB)+1.8(AB)+5(AM)+1.5(FB)=12sec for all of these.

Extra stuff for 18/0/43: WE.
During lifetime it casts like 15 waterbolts. Waterbolt's damage with +1000 Spell Dmg is like 822.6. I don't even wonder what is it's crit chanse, but if it's the same with the mage's one: 822.6*(0.8+1.5*0.2)=904.86. Thus, tanking in count 180sec CD: 75.405DPS. So, for 18/0/43: 75.4+929.51~=1005DPS.
