The problem is not that it is gameable or not. Even if it is, most researchers won't try to game it. The problem is that they will focus on optimizing these counters by necessity (they have no choices, it is that or goodbye), rather than doing what they want to do: great research.
I wouldn't call prioritizing quantity over quality gaming the ranking system, it is merely playing by its rules. I would call gaming it if there was some cheat (like you cite me and I cite you even if really we shouldn't), which may happen but I believe is rare.
It seems you have reduced my argument to the last part only. Google's system is pretty good even if you don't focus on gaming. By the way, even when it comes to websites, most users (admins) don't try to game the system.
