Finally a topic in which the person actually tells what he/she really wants.
Warrior:
Cape PvP: Definitely the most annoying build, with both KD and KB(except for axes) you can literally stop your enemy from attacking by spamming these two skills every time he tries to hit you, 2H Warriors can do catastrophic damage too.
Solo PvE: a 1H Warrior will level as slow as a Blader without a party, a 2H Warrior on the other hand will be able to do as good as a Rogue, one of my guild mates, a lv 36 2H Warrior, is soloing Bunwangs as i write this.
Party PvE: 1H = good 2H = good, as easy as that, if you're smart enough to use Vital Increase you will be loved everywhere even if you are 2H.
Job PvP: Warriors are more of a tool then a build made for fun, you will be hit extremely hard by nukers and you will be slow, on the other hand just as in PvP, if you spam KDs and KBs you will do great, at the end its all down to how you play your character.
Pros for 1h: Ultimate tanker if you use Vital Increase, its like a glavier and a blader in one.
Pros for 2h: More fun then 1H, can solo, does much better in PvP and jobbing and 2H swords look mighty nice.
Pros for D-Axe: Good looks + Stun, i don't really know a lot about dual axes.
Cons for 1h: A soloing 1H Warrior is just like a blader, which means you will level very slowly.
Cons for 2h: If you wear Heavy Armour a nuker can do simply hallucinating damage on you, be prepared to only grind on physical attacking mobs.
Cons for D-Axe: no KD and KB, which makes it much weaker in PvP/Jobbing then a 2H Warrior.
Rogue:
Cape Pvp: All depends on how you use your character, if you go under Stealth all the time, sneak on your enemies and 1 hit them, you will own, but if you simply run up to them like some sort of glavier you'll get owned unless the other guy is 10 levels below or you do a lucky crit.
Solo PvE: Xbow madness, i saw many Rogues, with decent crossbows of course, 1 or 2 hitting mobs 8-9 levels higher then them, if you take Bard as sub and you use Noise you will be the ultimate grinding machine.
Party PvE: Not quite as useful, i haven't seen many Rogues partying at high levels, most of them prefer to solo high level mobs, but at low levels you will be simply useless if there's already a Wizard in your party.
Job PvP: Extremely fun, i remember seeing a video of some Rogue, he was a hunter, went under Stealth and then went outsides Donwhang gates, then 3 thiefs come out(they can't see him), they look so tough and invincible and then all of a sudden, bam, dead one by one before they could even make a move.
Pros for 100% Rogue: Not a lot of SP required and you will still be able to do good in PvP and PvE.
Cons for 100% Rogue: You will definitely be a lot weaker, as i said before a Crossbow Rogue with Noise is the ultimate grinding machine, 1 hit mobs much higher without them all piling up on you.
I might start on Hera with you, Odin has such nooby parties that even in a party of 8 the xp comes slower then if you were soloing.
