I think about everyone that makes a Cleric sort of daydreams about making it a "Battle Cleric". And they can be pretty good killing mostly Un Dead mobs. That is their strength. But past like level 34ish IT is a real struggle to solo very quickly. But it works out to start duoing or full grouping because you get Complete Heal at level 39.
So you will have a few hard levels before you get CH. But there have been a few on here that have soloed to 60. It can be done. But in Velious there will be a BIG need for Clerics with the longer fights and harder hitting mobs. But I would not get in no big hurry to get to 60 because there is some nice low level zones even in Velious. I think level 28ish to 40ish will be the most fun zones to group in in Velious. The top guilds will have the top end zones tied up for months anyhow.
But a lot depends on your lifestyle and play style. A Cleric in a group is sort of a long term commitment. Its like you can't join the group and tell them 20 minutes later you are leaving. You have to sort of play for hours not minutes. A Wizard or a Mage can sort of say sorry I HAVE to leave right now and its not a big deal.
I find the longer I have played on here the more I do solo. But I have made enough plat to afford good gear to do so. So that helps
