There are clearly written rules. They are called the Inalienable Rights, and it is the responsibility of everyone in any position of power in BattleMaster to know and follow them.
In fact, the inalienable right to be inactive has been a part of BattleMaster since before the Inalienable Rights were codified, as you can see on the older Government Rules page, which is presented as required reading to every single government member upon their election or appointment.
If you have a problem with following any of these rules, or the other ones on the Rules and Policies page, then I'm afraid BattleMaster is not for you, if it ever was.
Yes I'm very familiar with that - I'm not saying people with positions of power should have the ability to tell players to log in and punish them for not doing so. What I'm saying is there was always that nagging worry that a general (or ruler, or whatever) telling people to follow orders is somehow borderline violating these rights - these were voiced to me personally, although as I've mentioned they never even got to the point where people filed complaints and Titans dished out punishments. I would also like to point out that I was making the point of how as an in-game general, for IC purposes he was very much (and should very much) care about whether people were following orders. It would be crazy if he didn't.
The thread is about "What prevents game to be competitive" and I'm just pointing out some of the things that I believe is lowering the game appeal for players - especially new players, which BM seems to desperately need. Basically, the game is not "gamey" enough.
