5 locks vs 1 priest 4 locks

[Bellman]

I have some thoughts,

I'm really having a hard time choosing between these two.
Someone who has one of these teams? how are you doing with it ?

I now sit with the following characters at level 24

1 priest
5 warlocks
5 hunters
4 mages

Should i try to level up a tank also and go for trinity or should I stick to these characters and do one of the two teams in the topic?.

Tips are very welcome.
