hows it going,
basically, As you are starting i suggest get every skill in each tree, theones you need ofcourse, no need getting dual axes skills and s&s if you are only gonna use one.
now, first you will want to figure out what combo you want to use for warrior, 2h Sword (Big damage, lower defence), Sword and Shield aka S&S (lower damage, but takes a heap of damage) or dual axes (good damage and quick attack rate). I personnaly have rogue daggers and warrior 2 handed.
I find the 2handed very handy for killing mobs quickly with the big damage, and the added knock-down and knock-back (mainly knock-down though) helps alot to overcome the pot delay and the lower defence, as the mob is on the ground 30 percent of the time after you use that skill, and then you whale on it with 150% dmg from the other main skill you et arly(the knock back skill).
from the start to lvl 20, you will basically want all the skills, except for maybe scorn (funny though, very funny - only for pvp though), but i find 2handed better for lower lvls compared to daggers, as you can kill mobs very quickly and not take much damage, whereas as daggers you would take 2 hits from a mob, you may only take 1 or even less, if your knock down is succesful.
I just leveled to level 20 last night, and after gaping from 15 onwards to save some SP, i decided to go for daggers from there on as main. i had about 750 SP saved and could get all the dagger and poison and monster mask skills i needed in the rogue tree. I also lvled the warrior tree to 17 with the left overs. from there on i will leave it at 20 until 24, lvl it up, and leave it there until 30, when you get another whole new set of skills available.
from 20 onwards you really have to start pciking your skills right, and how far up to level each one once you have acquired them. I highly suggest you start gapping to give you more SP, because if you plan to have the main skills, you will find yourself well short of the required amount needed, even though it is Europe and an insane amount is not needed.
so its up to you, and i might add the fact of lvling the warrior mastery up to gain access to heavy armor does help too, many people see this as the only reason to go rogue/warrior, but you can be very versatile in a party too, if there is only 1 tank, you 2hand, and if there are 2 tanks already, and dd's are needed, then you turn on dagger desperate (lvl 20 skill, gives you 75%more dmg for 75% less defence), and hammer away with it.
If you are soloing though, and happen to come into contact with a giant which is your level or within 4, then i highly suggest you turn off this skill in order to survive, because you will find yourself losing a lot of health fast, and not dealing enough damage to kill it in time. otherwise, turn it on an you will utterly pwn any general or champion mobs with them only giving 1 hit (if you use a skill on it).
but good luck with it, as far as gear and weapons, just try and find some bargains, and if you find yourself using warrior more, get a nicer sword and always stay up to date with your lvl, and maybe the daggers every few lvls, or the otherway round, depoending how much you use each. there isnt much use for buying sos or +5 weaps at that lvl, coz you will find yourself doing fine with one a bit lower, and at the rate you level at the early stages, there will be only maybe 5 hours before you can get a better weapon withoiut the money. from 24 onwarsd you might want to start looking though, if you want to be teh uber leetest.
good luck, hope i helped
