Play what ever job you want remember skill>gear>race and when i say gear i dont mean like galka running around with astrals, just be smart about what you equip
heres a quick run down of my experience with the jobs
War- tank and damage dealer, invite isnt as bad as most melees because of provoke
Mnk- all out DD, can tank but not as well as War,Pld,Nin. fun job but guarding skill is a pain in the arse
Whm- healer, i suggest starting out as this job if you want a adv job since whms are alwase needed.
Blm-fast leveling, ideal job for ppl with BNS (big number syndrome) good at makeing money but then again you spend alot on spells
Rdm- DO NOT LISTEN TO THE STRATAGY GUIDE! this is not a all around job "maybe in soloing or ballista but not in a party senario" this job will enfeelbe and heal mostly with some light nukeing/melee
Thf- utter hell to lv till lv 15 dont expect to many partys till then either, I say just grab yourself a bow and go soloing
my personal recomendation is lv whm to 30, unlock all adv jobs, then lv all those to 10ish to get a feel for them, again heres a very fast run down as i should get to class
Rng- nerfed but still fun, arrow burn
Bst-nerfed and i personaly dont like it, watch a rabbit kill another rabbit
Pld- tank par excelence
Drk- another good one for BNS patients, melee DD, stun whore
Smn- your support job will define what you do for most of your smn experience
Bard- enhancer
Drg- DD, jump is fun, not a party favorite
Nin- wasnt ment to be but Tank, enfeelber, puller
Sam- was ment to be a agressive tank but isnt, weapon skill master, keep archery capped
and heres a quick run down of what i beilive the new jobs will act as (this is just an opinion and odds are it is wrong)
Blu- im thinking like rdm but more geared towards DD instead of enhanceing
Corsair- party support, enhancer, maybe enfeebler, possibly some light dd
again this is all my opinion and should only be used as some thinking material go lv the jobs and form your own opinions
