Although it is negative, it’s hard not to be! GW clearly aren’t giving Dispossessed any consideration in terms of balance. Reducing the cost of heroes is great but we needed reductions in points across the army for it to be balanced with the other battletome factions. Ironjaws have seen a massive change in fortunes with new spells and changes to allegiance abilities and we’ve had nothing.
The only thing I can see as a positive is that if a book is coming out soonish then they could have already finished writing new rules for us. If that is the case you wouldn’t want to spoil it in the GHB. Beastmen got a book soon after the GHB last year and still had rules in it. Also the books go off to printers 6-8 months in advance so it is possible new rules have been worked on already, so they’ve had to make just minor changes in GHB.
