it would have been cool if there was a co-op mode or having batman coordinate (just have them fight side by side with you like in star wars battle front like DCUO has presented it. and they fight on their own corner) the bat family or the other teams bat man has created like the Outsiders or the more recent batman incorporated or the bird of prey that fallow his his instructions often while he does his own(us being playable) thing else where. and it does make sense for a siege of a city for that to happen. their his after all.
As a final good bye from Rocksteady. but they can only do what they know, and if they couldn't find people to help make those kinds of a features or if they just simply weren't interested in expanding their skill set , horizon wise yet it's all good they should go at their own pace and that's fine and I've already said a lot on it. I'll take what can from them and like it.
