Picking an orc is putting a huge target on your back.

Every goodie will be gunning for you.
Every outlander will be gunning for you.
Many evils will be gunning for you because they're evil.
Nexuns will be gunning for you half the time.
Imperials will be looking to boss you around.
Scions will be looking to boss you around.
Other Orcs will be looking to boss you around.

Orc is a very, very tough row to hoe for the new player. They offer unique RP that's very appealing and I understand wanting to play one, but in an RP/PK MUD they will be on the 'prey' side of the PK equation quite often.

I'm sorry that you didn't get the RP that you were looking for, but did you try to get a response from those who killed you? "Why you bash me down. I not did nothing?" is the kind of thing you'll often hear from Orcs (especially when they clearly, clearly did do something, of course.) Did you offer them your fealty if they'll leave you alone in an appropriately Orcish way? If so, I'm sorry you had a bad experience.

It might have something to do with the fact that a lot (a lot a lot) of Orcs tend to be throwaway characters that are played for laughs and have retarded, possibly obnoxious RP. Getting taken seriously as an RPing Orc is an additional challenge, especially in the wake of ORCORCORCBOATBOATBOAT!!!! (Which you may have missed.)

The fact is that CF has many levels to the experience it offers. From "Newbie Meat" to "Elite Master of Thera." Most people seem to settle in at the "I'm comfortable getting around, but get killed more than I kill, and provide decent RP most of the time." But we all start at "Newbie Meat." Giving yourself an additional disadvantage, such as playing an Orc or a Drow Necromancer is going to add to the frustrations felt at the "Newbie Meat" level of play.

The reason that certain classes (Rangers, Assassins, Warriors) are reccommended for new players is because the new player's weaknesses will be diluted by the class skills, rather than amplified by them.

I swear to you that if you roll up a Battle Ranger you'll find it a whole different game. A whole different game. Getting that first mage kill might be tough, but after that I think you'll be pretty surprised.
