New to Turn 5, any advice?

[Spiritus]

So Ive been pugging T1-4 for about a month now sense my static broke. We never ended up getting into T5. I'm i90 and pretty much have given up on getting BiS before 2.2, but would like to at least clear T5. However unlikely it may be with a pug group, I would like to try.

I normally build my T4 groups and was just looking for any tips on party build (Obv Sch/Whm and such things). I know about the 4,400 minimum hp, but other than that I'm pretty much in the dark. So any advice from a tanking perspective and group building is appreciated. Ive watched Mr. Happy guide several times and Ive read a couple guides so I know the mechanics to some extent, but there's always the little things like how often certain mechanics come up you only get from running. In particular Im interested in how groups normally handle the dive bomb phase.

To those that will think or say "Static," unforunately my schedule between work and other activites doesn't allow me the ability to make a consistant time or day of the week. Trust me, I would if I could lol.

Edit: For any researchers out there, I'm workin on conj next to get SS <.< I'm terrible I know lol.
