This OP reeks of trolling but yes. It is a pattern. You can memorize it.
But you shouldn't have to.

The game is "reaction" based but yet a lot of people are left to play by memory, because of the game's flaws/problems.
A built in 0.3 sec delay (They say it's reduced to 0.1 but I somehow doubt people who already have 100 MS will appreciate an additional 100 MS on top of it; worse, 300 MS if outside of "hard" instanced content).
Constant lag spikes due to data centers.
FIOS users are basically totally screwed currently.
Etc.

I am one of the lucky few.
I have very little to no lag; but even I can notice that massive internal delay. People don't have to deal with this nonsense in other MMO, why should they have to put up with it with this one?
