Just out of curiosity do any of the front line members have any skills to pull or push back enemies as you attack for ranged members to be more effective? I've only heard mention of knockdown listed so far, or spells like web or tangle for example. I think it would be beneficial if they could some how bring aggro to them, or pull them closer to the party without having to rush, or have the capability to push them back a few yards and hold them for a stun so you could turn your attention to another threat briefly. Is there anything in the game like that?

Yes there is. Fighters, Monks and Chanters have these abilities.
