Depends on how your server's balance is. But since you are being "camped" it means you are very few reps. So just make 8 man premades late at night.
Actualy on servers with a very high imps to reps ratio the reps can get geared so much faster it's not even funny. Wait till 11-12 when most people go to bed and spam wzs with 8 people. It worked wonders for my friends who rolled republic.
