What's another well rounded class?

The warrior/monk is very easy to use, deals good damage, can take a lot of hits, and can heal him/herself. I just wanna know some other class combinations that have the above qualities for pvp and pve, and I'm asking based on general opinion, since I know that guild wars is very balanced. And the general opinion on wa/mo is that they are very well rounded..so I wish to know what other combinations are well rounded and easy to use. thanks.

Personally I love playing my R/N. Being able to poison mobs and summon minions is very nice in pve.
