Cross-Class skills while leveling

[Wotif]

So I'm leveling with the intention of becoming a WAR (currently MRD 21, GLD 16). I prefer running dungeons to questing, so is it worth leveling PUG to 8 for Featherfoot and Second Wind? and Lancer for Keen Flurry? Currently I'm running Flash and Convalescence from GLD, but I've got more slots and I'm wondering if it's worth the time to level these.

I dont know much about tanking, but I know enough that it's worth getting Provoke for your WAR

Featherfoot is one of the cross-class skills you'll almost always have in your selection as a WAR. Second Wind is also good, but gets swapped out depending on your healers and/or what else you need at the time. Both are definitely worthwhile.

Keen Flurry's not such a big deal. You can't use it as a WAR, so you'd only get use out of it for 9 more levels. If you want to level LNC anyway, feel free, but I wouldn't make a special effort for it. Edit: And yeah, for that matter, spend that energy going 6 more levels on GLA for Provoke instead.

I'm only a paladin not a warrior but I would just level up gladiator and pugilist because you can't use lancer skills when you get your warrior job. I would highly recommend getting your gladiator to 22 for provoke since you're already at 16. Here is some information about cross class warrior skills I found in another thread:

Featherfoot - One of the best defensive skills we have access to. Dodging works on many boss skills, including magic damage.
Convalescence - Increases effectiveness of heals incoming to us. It does stack with our Wrath stacks. However, it does not work in conjunction with Inner Beast or Bloodbath.
Provoke - Another really great skill. Most consider it worthless because they don't understand the mechanic. It is a skill that matches the highest enmity against the target plus one.
Internal Release - An offensive skill that we can utilize for defensive purposes. Since Inner Beast heals for a percentage of the damage we do, this includes damage done through a crit.
Second Wind or Mantra - Second Wind is a useful skill that helps recover health in a tight spot and can be used with Inner Beast to help maximize the health restored. Or, you can opt for Mantra to use with max Wrath + Thrill of Battle + Convalescence for a total of 55% more healing.

Warriors are getting changes in patch 2.1 coming this month and their healing mechanics are being changed. So the healing information might not be accurate anymore.
