conjurer vs. warlock levelling

[grayFalcon]

Hello everybody!

I'm a level 10 mage now, and I'm trying to decide whether to be a conjurer or a warlock. Generally, I prefer being a support player, so a conjurer seems to be the logical choice. But I keep seeing complaints about conjurers being impossible to level and getting nothing from healing. Now that would be a problem, because I don't really have horribly much time to play. And to do any serious support, I'd need to get to a relatively high level. So the basic question here is: Is it possible to level a conjurer reasonably quickly? How do I do it?

Is the warlock insanely much easier to level? If so, I'd go for a warlock - after all, they are kind of supportive too, just more in a "big bada-boom artillery"-way, rather than the ambulance-way of the conjurers...

Thanks a lot in advance,
