About minion health regen+leech

[Nepster]

I have been trying to make minion build and invested into health regen and leech from both skill tree and passive tree, but i feel like they have absolutely no effect on my necromancers minions. Are they worth of investing at all or should i just focus on damage or armor ones instead?

Health regen only works on low levels, while minion hp is low. In endgame regen is worthless. Leech is good if minions have enough health to survive and enough damage to leech health back in short time.
While doing compaign on low levels you should get helmet and/or belt with minion health regen. It will have much stronger effect than what you can get from passives.
