The new wounding is much more consistent with blood loss in 3rd edition (3.0 or 3.5). After all, blood drain is con damage; so it's only logical.
Better still, the old Wounding was a nightmare of bookkeeping. OK, on my turn I have to remember to deal 2 hp to Zonzor, 1 to Thimbleton and 4 to Thrush... bah! Con damage works for me.
