What Krusty says above is probably true about the whining, as it is ubiquitous in AH for anything and everything.
I don't agree that it would reduce peoples willingness to take troops for a capture, as it is done now anyway. If anything it would increase people's willingness to do it. (it is cool getting the wtg from fellow teamates)
As far as 'stealing' someones capture, that happens too. I've been to a maproom first and let troops go, then someone following releases and gets the 10th troop in before mine, getting the capture and the 'maproom destroyed' message. Sucks but thats how it goes, like kill stealing by shooting at a mortally wounded opponent.
Vast majority of the time though, the base capture is done by that one guy over and over who gets no credit or public recognition. I don't think it's a big deal, and would take AH two seconds of code writing to make the change.
Speaking of AH, I wonder if they actually read and effectuate any of these suggestions, or are we just wasting our time even putting forth ideas here
