For players just starting out these are the two classes I recommend.
Blacksmiths advantages are free greed so you don't need to worry much with looting and will never need to get an hbp for quick looting as well as having a 5 skill point 5% neutral resistance passive,the ability to repair weapons until you get a zipper bear card for a higher end weapon to counter power thrusts weapon break chance while maintaining decent aoe and having ore discovery to gain a ton of oridecon and elunium while mobbing. Great option for starting a foundation with option to transition to a pure forger later on if you elect to change your primary class.
As for rogue the advantages come later on with gank being an early economic boost until you can hunt bigger game and aford whatever methods of making zeny you ultimately decide on. With shadowspell for aoe and several options to benefit from atk builds as well now it is viable in pve to start a foundation but likely will ultimately become an alt used in pvp and woe. They have insane evasion and benefit from a shield without a ton invested and they don't absolutely require any expensive equipment to be sustainable at least to level 110 or so which is high enough to bring in a steady flow of zeny from gank and aoe looting. I won't be specific on builds as it depends on what equipment you wind up with and how you like to play what will ultimately work for you but these two classes I strongly advise for newcomers to consider as the most common issue I've heard is the lack of a reliable means for a new player to make zeny. If you are strapped for time you can also benefit from buy vending with any merchant type and buy low,sell high; The most basic principal of bussiness.
As for priest alt if you get to ab it makes leveling any character much easier though dual accounting can be tedious at first. You will also have it as an option to get in any ti group you want even if it is just to gain magic stones from the badges. Guilds will love you if you main ab also.
Not exactly a guide but I figured I'd put this out there in the event any new players actually find their way to the forums looking for direction.
