I see your point, but if that was the strategy that you used against a person IRL, then they'd start disrupting you or else building up their primary bid where your primary bid is. Then disrupt yours at some point. I think IRL, different strategies would start to evolve.
A metagame. Yes, absolutely. If you were to play this game IRL, you would certainly see that. It would have been sweet if your opponents in-game would evolve their strategies in this way, but that's a nice-to-have which I'll gladly forego in favor of Obsidian fixing numerous other bugs.
