AST into Ranked...I didn't exactly know how to heal PvP, besides FL and Feast 8 v 8.

Team curbstomped, I was told to never go into ranked ever again. Fair enough. I was bad.

I got nothing when I asked what I could do better though.

Tried my other 60 classes:

BLM: I only have 1 GCD and Sleep, Freeze, and Fire IV are all on it. Nightwing has a long CD. Who do I even attack?! Do I bother with Thundercloud? I'm confused.

WAR: "Burst Someone" Uh... The BLM or WHM? I can't do both... Once again, confused.

Read a bit on this forum, and I've decided to go level BRD. The idea of Barraging Empyreal Arrows at people sounds fun in 8 v 8 at least.

Questions I have:

Where is a new player supposed to actually learn how to... well. PvP?

How long should a player be in 8 v 8 before they finally can try 4 v 4?

How do I practice PvP rotations? Is there a "PvP Dummy" anywhere?

How much attention should I actually pay to people telling me to just get out of ranked?
