Best pvp group

What do you think the best pvp group e.g. for the hall of heroes is?

I think a couple of good ones are

5 air eles + 3 monks

3 monks + 2 eles + 2 warriors + 1 mesmer

i think that 3 monks are essential, 2 at the very least, its also good to have 2 or 3 eles as they cause the most damage and the warriors to tank.
