The thing is, we have some data. Precisely this sort of behavior came very close to destroying the Axis v. Allies arena.
Good point. In the case of AvA I wouldn't condone such behavior - the numbers are small and the priorities at the top of the AvA list are clearly immersion first and "winning" a distant second.
Why the difference between MA and AvA attitude on my part? The acceptability of such behavior depends entirely upon your goals. Are you playing to win or are you playing to have a social hour that you prefer to win, but with winning a definite low priority? If you are purely playing to win, then one less competitor brings you that much closer to winning. If one can achieve this by means of social aggression (within the limitations of the rules), then that is a legitimate option. The risk, of course, is alienating your fellow players, and in extreme cases driving so many people out of the game that it is no longer meaningful to win. Since it could be bad for business, HTC may choose to ban such behavior, although I find it difficult to effectively police.
Personally that is not my mindset in Aces High and it's usually not be in the best social interest, but the presence of such a mindset is simply a feature of any competitive environment.
You may revile it, rail against it, etc, but why not simply learn to ignore the taunts and shoot the other guy down? In the end, that is the ultimate "counter". Inability to meaningfully ignore the taunts shows psychological weakness on the part of the taunted and let's not forget that psychology does play large part in our combat hops. Greed kills more often than ACM.
Is it good sportsmanship? No. But sportsmanship is a social ideal, not a competitive restriction. So - would you rather everybody like you or would you rather gain an edge on the competition? It's a tradeoff, a calculated risk based on what you value most in this game, nothing more.
The people that have posted here supporting good sportsmanship clearly lean towards the "social benefit" end of the spectrum. I respect you for that and I agree. That's how I conduct myself.
The people who taunt clearly lean towards "playing to win." I respect them for that (as long as it's kept out of struggling areas like the AvA), but I disagree and find the pursuit rather silly.
Edit: the guys who don't taunt and still win - well you are just that much better than the taunters and I salute you for your skill.
Edit edit: So does it matter? Yes, if you want others to like you. Yes, if you want to foster a positive and encouraging environment for everybody to learn and fly in. No, if all you want to do is win.
