Well now when im soon gonna start play with 5 accounts i just wanna have some questions about what classes to run?

Ive checked alot at running 5 shamans, 3 ele/enc and 2 rest because would it be good to have 2 healers using the Chain Heal on 2 different target help all ?

Because i think its better to have a range or caster when im gonna play 5, i mean i dont wanna have 5 different classes yet due to im pretty new to the 5 team setup :P have great experience on a 3team but when i didnt use macors and shit :P
