Every door has a "don't stand in this spot" mechanic and most of them are quite visible. These are all, essentially, the same mechanic and can be treated as such.
The first door has a magic dispel, second has a poison dispel, third has a disease dispel (fourth has a curse? I never paid attention at that point). All of these are, again, pretty much the same mechanic, just with different classes being able to handle them. The poison dispel can be nullified through proper interrupts. In fact, I believe you can simply mark the mobs before you even pull the boss and assign interrupts to those marks. If you assign interrupts to all three of them, you should be fine on the second door. Also, interrupts, aside from Avenger's Shield, are not disruptive to rotations. Interrupts are off the GCD and should never lower a person's DPS unless, again, they are a prot pally using Avenger's Shield.
So, at this point, you've basically got different versions of two mechanics. Treat them as such!
