There's an assumption that HT wants to do something about HOs... You might want to give him a call and ask first, before telling everyone what you think HT ought to do about any particular issue.

That goes for HO's, ack lethality, moderation idiocy, etc. There's a lot of posting going on here about why one feature or another is broken, stupid, or whatever, and even more posting on what HT ought to do about it, but frankly none of that matters if HT thinks it's working as planned. As a simple purely hypothetical example, if random acts of moderation get rid of a few vocal players that are perceived to be detracting from the game, then it makes sense to keep such a system in place. Getting a moderator message saying "it's my game" makes HT's position on arena moderation very clear. The same goes for ANY game feature, from ack strength to coming up with some way to discourage headon attacks. HT will set up the game to encourage certain things, discourage other things, and whatever he doesn't care about he will leave alone.
My personal guess after playing HT's game for 7 years is that HT doesn't care very much about headons, otherwise he would have done something about it by now. I don't personally care so I've never asked, but anyone who does ought to pick up the phone and ASK before making any assumptions. In my experience, HTC is very accessable and willing to speak to players on the phone about almost any topic, so it's worth a shot.
