Several PVP Questions

[MystinaValeth]

Okay so I have several questions about PVP, more specifically about frontlines and white mage. Any help would be most appreciated ^^

1. Does the FC action 'The Heat of Battle' increase the amount of PVP EXP gained?

2. I want to eventually get the ilvl 100 PVP armor (which requires a PVP rank of 38) and I'm currently rank 17. About how long will it take to reach rank 38?

3. I play white mage in PVP and I was told to wear vitality accessories, is this true?

4. I just got a full set of ilvl90 direwolf gear for my white mage and I noticed in the description of Carteneau Flats it says "Item Level Sync:80 - While synced, all item stats are adjusted and materia bonuses are ignored". Since my gear is going to get synced since it's 10 item levels above what is allowed, should I not bother with materia because it is going to get ignored?

5. Does regular materia work in PVP (such as +vitality) or only PVP materia (such as +stun resistance)?

6. If materia doesn't get completely ignored in frontlines (which is the only PVP I'm interested in), what should I slot into my Direwolf armor as a white mage? Should I go for more vitality? or go for stun resistance to try to prevent my spells from being stunned when I'm using Surecast/Equanimity? Or something else?

7. As a white mage which PVP actions/traits should I get? (I currently have 2 in Sacred Prism, 1 in Equanimity, and 1 in Purify. I'm planning to get Equanimity maxed, then Divine Breath, and then eventually Focalization.)

8. Any other tips or things I should know?
