A mid-point option, though one less kind to spearmen, is to keep the interrupt--rather than a bonus attack--and drop the in-fighting bit. This is mechanically much simpler, but takes away much of the threat of spears and polearms. Historically, the primary purpose of adding a spearhead to the tip of an otherwise swung/hacking polearm is to keep people at bay. Granted, a line of spears would still be intimidating as everyone of them could potentially be granted an interrupt. However, this would be less of a threat when facing another formation.
