Why isn't my Paladin resurrecting my guard droids?

[DGDobrev]

The Paladin hero can resurrect everything - plans, mechs, lvl 5's, etc, provided he has the resurrection skill.

The Paladin unit resurrects level 1-4 living units. No mechs, no thorns, no 5 lvl units.

As such, you should be really careful. Playing with droids is interesting and provides some easy time. However, such a gameplay requires that you split the mechanics stack in 2 equal parts, so that you can fix both the battle droids and the mechanic droids if you suffer casualties. The other 2 stacks are up to you. Some strong ranged units - like cyclops + demonologists or Inquisitors + Demonologists will fit here nicely.
