I'm looking at my new MK 2 Circle rules, and I notice that there appears to be no more SPD+5. It's all +2" of move now.
It's not just circle. The Axer's animus, for example, now grants +2".
I always thought that SPD+5 was intelligent game design, since it put a cap on stacking abilities. You can now stack Dog Pile, Bounding and Hunter's Mark with Warped Spd for a Feral Warp Wolf that charges 14". Admittedly, with eKrueger in MK 1 you could get him up to 12", but still.
I thought they nerfed Advance Deploy to blunt the alpha strike, but by changing SPD+5 charges they enabled some alpha strikes that weren't there before.
I don't actually think it will unbalance the game or anything, but it does seem like the opposite of what I think their design goals might have been for MK 2.
