i'd say paladin. cause usually if youre a newb then you die often so when you're a paladin you could be a tank and a healer (you can have strong moves and heal yourself and others)
If you are just starting out I would recommend a Paladin. They are one of the easiest classes in the game in my opinion. Especially starting out. They may get a bit more in-depth at level 80 but that's if you want to be top notch. I used to play a Paladin and on the first levels it is very simple. Plenty of buffs, and you don't die too easily. And well, simply put, retribution is perfect for leveling.
