Hello everyone, I need your help regarding legendary chaos invasion(everything else is ok).
Before we start - I use early chaos invasion, so it starts at 65. The problem is... at 80-85 empire dies. Actually everyone dies. I barely kill in a couple of turns "my" wave of beastmen and start to transport my armies to the empire to help them, but by the time i'm somehow ready there are around ten of them already on my doorstep. Ah, also ruins spawn chaos armies, yes-yes...

Well first problem is that I wage war on 3 fronts - against queek, assasin rats and third - chaos.
Considering amount of territories this is a problem - territory is just too large, thanks god at least Settra likes me.
2nd one - I conquer Eight peaks too late - around turn 55, may be even later. In exchange I have no vampires and scavens on my starting base(and +30% research from ikit). Tilea too, died in vain.

I really think that with this combo without coop legendary invasion is impossible, as I'm just cannot help ai enough to defeat chaos, am i wrong? May be I do wrong starting movies? Or do I need to mass spawn magic ranger armies after Eight peaks(the are OP, damn)?
