the problem you have, and that everyone else have, is that block generation is really weird, it's not stable at all, so the theoretic formula of 1 block per minute is screwed, sometimes you see 2 blocks generated in few seconds, sometimes in a couple or more minutes, so this is hard to time at the right moment and often is a matter of luck

of course if you are facing someone who sends a move very quickly while you take time to think and plan your moves, and a block is generated fast before you decide, you probably are dead
on the other side, could happen the opposite: the player/bot who sends the move asap, and doesn't protect his move setting his first waypoint away from enemy, can have his destruct to happen earlier than he wanted thought, and so the hunter is exposed to the other player that took more time before pressing destruct

But i agree that the main problem is that the blocks are often too fast, this is something to investigate but i don't think there is someone cheating, the problem is just that there aren't stable miners (IMHO) or worse, there is some bug in the block generation alghoritm (I don't know if it's custom for huntercoin or not, i think it's a namecoin port but maybe namecoin suffer the same problem, but not being namecoin a turn based game, It can be gone unnoticed)

anyway faster blocks means someone couldn't handle many hunters and this is a good think because it leave spaces for other players to collect HUCs, on the other side if the game mechanics keeps being so simple, the chance that the bots take over is high (hint: ammo/armor system + cooldowns + power ups)
