Ideas to avoid "win at all costs" but still rank games/players

Alright, Ironclad doesn't want people coming up with an optimum strategy every patch, and then players going online and finding that that strategy is all that gets used. I can understand that, seeing a glorious game reduced to a calculated number of mouse clicks every single game can get depressing. I have to say though, many of the most popular strategy games (Starcraft, Warcraft 3, Command and Conquer, and many others) had quite a few optimal strategies to choose from, not just one godlike strategy. If you wanted to be slightly less optimal, your strategies could still work, because it catches the opponent off guard. Once you start playing these games a lot, it becomes less about which units counter what, and more about which overall strategies counter what. Rush against techers, expand against turtlers, etc.
In other words, I don't think most gamers think it's a big deal at all that some strategies are generally better than others. But, it's all about probability. This game seems to be one of the most balanced I've seen as far as that goes, so I don't think there's any reason to be scared of a ranking system.
If indeed Ironclad is worried about gamers ripping the fun out of the game by playing only to win, perhaps there are other things that could be added to records in order to balance it out. For example, track wins, track losses, track drops (like all other similar games), but also track other things, like how many planets the person has captured in total, how many research points they've spent total, how many trade ships they've had in total. The system for pulling these records is already in place, as you can see everyone's totals at the end game summary charts.
You won't adjust peoples' play styles by having zero rewards. If you want to diversify play types, then reward players based on a diverse set of characteristics. I suspect that eliminating a ladder system altogether is going to make competitive people (the majority of gamers) ask themselves "Why even bother?" after a while. From the beginning of video games, gamers crave rewards. If you find a way to cater to that need, as well as achieving your own goal of promoting alternate strategies, you're going to do nothing but increase your playerbase.
