i will have to heavilly disagree on objective cards. Yes we need upgrades, so do everyone else, except upgrades on a stormcast or ironjaw provide a better return from the investment than for us due to the quality of their warriors.
The bigges problem is that if we allow our opponent to gather objectives while we are doing the same we are gambling on them not having the right objectives. Moreover even if we find ourselves equals in glory, we are alreadt behind because they get more from their glory than us, and we "wasted" X number of activations to already be behind.
That's why i ditched them. Yes you can score them early but neither our warband, ploys or upgrades are fit to be played seeking a third turn dominance where we can score quickly enough to justify giving up room to breathe for our opponents if we aren't already ahead. We are a fast aggro deck, we just attempt to roll over the opponent, force them to stop from gathering points from objectives and using as many ploys as possible that can force opponents to charge at us (side step for example) ,to waste actions (landfall, insensate, blood rain) or anything that provide the means to have succesful attacks (sidestep, landfall and any card that gives us extra dice or free damage/extra attacks).
The three successful attacks in one turn is actually not hard to achieve if you set it up for it. If i get it first turn, plus the charging one and some play to guarantee attacks i am pretty much golden.
I think people in general are too conservative with Garrek's warband, and against the warband i have the most experience against (stormcasts) this is a exercise of futility.
