Sorry, but no. I played vs FEC with IJ many times and i see unit what normaly killed my unit of 6 GG easy, cant kill Ishlaen guards 3 combat phase and FEC unit lost more than can do GG w/o 5-6 WAAAGH. Last time my 2x5 brutes and 2 megabosses cant kill 20 sequitors with -1 hit debuff. 640 points with WAAAGH cant kill 400 with debuff! I just dont understand it.
I will ask ppls play with IJ with decreased price 2-3 times (120 GG, 140/380 boys, 160/580 brutes, 100 shaman) and try write about result here.
