I'm quite certain they are aware of this and this is what they meant for. It is my understanding that some of these pacts are meant to be this substantial to help move the game along quicker when it gets to those stages.
I'd be willing to bet they have noticed it at one point or another or will before it releases, but I wonder if they really had it in mind when they created the tactical slots buff.
I don't mean to make them sound stupid, but it really does seem odd. I think you're right Annatar, but this does seem to be a bigger buff then the rest, if only to some people, scenarios, and strategies. (I was personally thrilled when I saw that the cap would now be 39)
My mistake Pbhead. I thought the Advent were like that too. I'm glad you pointed out that now they can hold 3- this still keeps it relatively the same as before then.
