Caster group question

[Norathorr]

I play a shaman at lv 47, but three friends are thinking of starting the game too. One wants to play ench and the other two were considering druid and wizard. It is my feeling that perhaps a necro would be a better replacement for the wizard and im not sure about how a druid fits in too good either. Could be nice to bolster healing for shammy till torpor I guess. But velious mobs have big hps and resists, are wizards really a decent classin this era or would dotting mobs down with a necro and charm pet work better?
