How to be a better MNK in PvP +Feast?

[NoelNoel]

I wouldn't recommand opening with Sommersault, Perfect Balance is a better idea, and don't start using offensive OGCds until you have GL3 and Twin snakes at least. You might even want to wait for your target to have the effect of Dragon Kick on them. Don't use blood for blood if you are being targeted first. While you build GL3, Twin snakes and Dragon kick, you can weave Bloodbath, Keen flurry, Featherfoot and Internal release.
Axe kick is up to you, you can use it to save someone or yourself, or regain GL3 right after using Tornado kick.
Pop Mantra when you are close to your teamates, healer will be happy.

I feel like because over somersault kick's fast CD, it's better to use it for opening as opposed to PB. I tend to PB when I want to olm punch someone's buffs off, whether it's a range DPS about to burst or a tank or a healer.
