Are you going team hunt with 1 or 2 druids?
As an ED who used to hunt there a lot, if you are the only druid I would go with mana instead of life leech, given that you will be spamming sio and that consumes a lot of mana.
If you still want to use a life leech imbu, maybe a good choice would be to imbu a bear skin, or an elven mail (in this case you can also imbu holy defence to help you with the chains damage).
If you are going with 2 druids, maybe you can try life leech on the rod. However, in that case I would use a cobra rod with crit and mana due to the life leech amount of the cobra rod. Despite Soulhexer is currently the BIS rod, I believe it is only better than the cobra rod if you were hunting Dark Thais or Ebb and Flow, because of the ice protection.
Hope it helps!
