Increase your DPS using server lag

There are many ways to increase your dps as a caster:

Gear -> Spell damage, Spell hit, Spell Crit
Talents
Player Skill -> Spell sequences, reaction time, ability in situational encounters
However, as you progress as a DPS caster class, there starts to become a ceiling to your dps, something beyond the control of the 3 points above. That limiting factor is server lag created between your connection and the server which can be anywhere between 0.1 seconds to a full second of lost dps per spell!

1 second doesn’t sound like much, but lets break it down in an example boss encounter:

In Gruul’s Lair DPS is vital due to the incrementing grow stages which make Gruul hit harder on your tank. There becomes a limit to the amount of punishment your tank and healers can handle before it is a sure wipe.

Here you are with your fireball spell that takes 3 seconds to cast (with talents of course) shooting away trying to take him down (as well as top the damage meters) in this 10 minute encounter. So if you could chain cast your fireball spell for that whole duration you should be able to cast 200 fireballs, well not with server lag. This will bring the amount of fireballs you can cast down to 150! that is a 25% drop in your overall dps the entire encounter.
