I think they should add a world clock to overview so as to allow corresponding attacks, and I think that if incoming attacks landed within a 2-3 second window they should register as one large attack so as to allow smaller guys to combat larger foes.

Doing this would give the smaller alliances at least one tool to fight bigger guys with increased need of precision and team work it this form of war fare is balanced and allows little guys to hold there own in alliance wars against larger guys. And yet the bigger guys can still use shields as the smaller guys are always forced to use.

It would close the gaps in the games war mechanics without disrupting the troop stats. I also think it would increase shield sales making the company even more $$$
