What class should I start if I begin on Red P1999?

[Solb]

Just thinking of making a new character on Red. What would a good class be just starting out? And why? I am totally ignorant as far as if spells land with ease, often get resisted, if mage pets are useless in PVP, if melee land hits on casters well, etc., etc. So, any input on these thoughts as well as what class would be good to start out with would be nice.
