Cheer up, I don't think Unstable is so bad thing in the end... Of course it sucks, but I still won't sell my army or stop playing them, we just have to play right.
So, The Drakenhof Banner, a Varghulf and a Black Coach is nerfed now. Let's start from that.
The Drakenhof banner was too cheesy in 7th edition, so now it got nerfed. The banner is too expensive now as it can only regenerate wounds caused by enemies (and crumbling when the general is dead, but usually then the game is already done

) so it's not necessary anymore. Or at least good. I think Flag of Blood Keep is going to be taken in 8th edition instead of The Drakenhof Banner, as it's cheaper and better against shooting (watch out for those Flamers and flaming Bolt Throwers!

). So all in all losing this banner isn't
so bad thing...
A Varghulf is now easier to kill, but it needs just some tactical eye. Just keep the beast out of the too big combats. it can still destroy war machines, fast cavalry (if your opponent uses them anymore) and even Knights from flank in rare situations. As Varghulf got Thunderstomp it's even nastier in combat!
A Black Coach works just like before, it just got better in 8th edition (it gets faster abilities, Str7+ autokill is gone etc.). Just like Varghulf, you just have to play it right, it's not good gaming when you charge a ranked enemy unit with a chariot. :lol:
I don't think it's very big deal all in all, it sure nerfed us but we are still playable.
