New to Raiding, Where do I start?

I'm currently a ilvl 390 PLD/DRK who wants to get into savage raids.

Met my old static via PF and has recently dropped the static due to schedules being a problem. I only have one savage clear to my name (o5s).

I'd like to get into doing more savage raids but I have no clue where to start. Where should I start?

Start by watching videos for O9S and O10S. Once you understand the fights, join learning parties or create some yourselves for O9S and work your way up.

On Shadowbringers? This raid tier is pretty much done and it will be hard for you to find decent people that still have to clear that tier.
