I think the trick is the +1 range. Less damage or more CS won't change anything unless its extreme, I can literally just sit there and plink away at the city until its dead. The only thing that change would do is slow me down a bit, but also grant me more xp once the job is done.
I think the +1 range is probably the best bet, though it might be a bit too strong with the new damage changes.
Having just done a quick hoplite rush, its quite sad how weak the hoplite is compared to the lonely archer. With hoplites I wind getting draw in and mucked down, with the archer rush I just move in and win....its so easy in comparison.
