Yes, leech is broken. The amount of healing gained needs to be cut by half or more (testing would be required).
I've been playing with a friend who plays a knight with the lone wolf and leech traits. Most of the melee attacks against him cause him to bleed and instantly heal him. At first this would heal him about 1/2 of the damage, so the skill was effectively a 50% damage mitigation skill against melee and archers.
However, as we have moved on toward the end of the first map leech has starting healing him for the amount he is hit for or sometimes even more. One battle had a number of archers which were lower level than us. The archer and melee attacks were effectively healing him. Their damage was lower than the leech heal he was receiving.
To abuse this broken skill further is to have blood letting on hand. My character has blood letting and if things go bad like a bunch of fire damage I can cast blood letting on my friend and it will heal him to full hps. Right now he has about 700 hps, as long as he has around 20 hps left I can heal him full. That is a 600+ hps heal, instantly. My int is 7 and witch craft is 1.
For comparison our companion hydro mage has 13 int and 3 in Hydrosophist. The largest heal in that line currently is strong regenerate. It heals about 180 hps over 2 turns.
The healing amount from leech needs to be tweaked. Even encounters with a lot of elemental damage are trivial with how much leech heals, especially when combined with blood letting.
