I'm completely okay with no more using it, unfortunately, as Jack said, it's a word deep-routed into the community as it describes a specific strategy. Chokepoint sure could work but it imply more the narrowing of the frontier than the pile of hard-hitting stuff in it.
Maybe, as the community slowly expand (and it will, with AIW2) and the "old hardcore player-base" (which I'm only half part of) becomes more and more diluted, the terms like "whipping boy" might fade out.
But right now, changing the community will be hard.
However, your point is interesting. I'll try to avoid that indeed confusing term.
