What is a very popular PvP server, and what character is fun to PvP with?

A good guide would be greatly appreciated...thanks

Shadowtown has been Heavy the past few days, USWest PvP - Also has a fairly balanced Republic to Empire ratio as far as I know, hit me up if you intend on coming

I like to Pvp with my Sentinel (marauder), and I've tried sorcerer (sage) a little bit which also seems cool.

Scoundrel (operative) my main which is healer is not so fun, but if specced dps it would be.

I personally find healers to be the most annoying to PvP against as a Juggernaut (Lack of interrupts I guess).

But PvPing on my Jugg is awesome fun, always top DPS.
