Some thugs + several hundred undead + rigor mortis maybe? Hmm.... I dunno... Darkness? Ghost grip spam? I can think of a dozen ways to stop such armies as Ermor. Judging by graphs, research wont be a problem very soon.
Zeldor also complained that poor, weak Ermor chaff cant deal with teleporting SCs. Then, of course, it turned out that Rigor Mortis is still there, in the spellbook.
By the way, such rethorics... 'now that I see your raw might... we stopped them just in time...' - I believe it was used by every aggressor who cared about his public image over the history of mankind.
