E/Rt...will it work

and are there any good builds..?

Do you mean Prodigy Ritualist or true E/Rit?

My guild was going to replace the elementalist/monk in our build with a ele/rit. But this was found to be a bad idea as the ele/rit just couldnt keep the spirits up. I recomend if you want to have spirits in your build use ritual lord and spawning power to help keep the spirits up for longer. Otherwise they wont be there when you need them.
