new to game many questions

[Felicity]

hi all im new to p99 i havent gotten anything very high on the game.
i am wanting to know how all the classes rank in order of best to worst. in regards to what im looking for in a class/playstyle. casual.

im looking for survivability, possibly soloability or atleast groupability with my wife being a mage. thinking but not 100% of possibly a melee class sk pal ranger monk ect. something strong that isnt going to be super squish.

not sure if sk or other classes get heals that can sustain them without a proper healer or not. also depending on what i choose does having low starting stats matter like gnomes humans erudite elves usually have lower str and or stamina in the begining. id rather not have to play troll or ogre as they are not what a girl desires to look like lol.

Please leave your comments and info here any advice is welcomed.
my goal is to group level and possibly be a casual raider end game someday but not in a rush for raids. my current goal is to have fun be able to progress in the game without feeling like im not getting anywhere or like im too weak to do anything.
