Regarding the posting rules, I've never had an issue with them. The rule serves multiple purposes.
1. The placement of abilities and weapons can be cross referenced with the character's vault and approval posts, if necessary, to ensure they aren't making things up about their characters.
2. Not all attacks are done in a fashion that makes everyone see the attack as an attack. We've had multiple nationalities of playerbase on this site, and English was not always their first language. Bolding normal attacks allows staff members who are grading jobs/events, and other players who are fighting PVP, to know whether or not somebody intended to attack even if it is difficult to understand from their description.
--To take this further, even those who have English as their first language are not always clear. Sometimes they have even believed that they could deal a certain amount of damage with an attack (like throwing a box - this was not a registered weapon - at an opponent) when there was no indication that this would be appropriate or acceptable.
3. Updated magoi/stamina count allows the person who is writing the thread to make sure they are keeping appropriate tabs on their expenditures, and allows the staff to easily cross reference what the player thinks they spent and what they actually spent (due to the requirement to post what abilities you use, and to bold them, it makes it easier to tally them up).
4. Word count - gotta keep track of how much you write. It is requisite in completing threads, and so long as they look about right the staff member may be able to skip the step of verifying you've got all your words there. Your thread gets graded faster so you can get on to your next thread and the staff member doesn't have to perform additional steps in completing the grading for it.
I'm sure some members who are very thorough ensure every requirement is met with flying colors and don't believe there is need for the posting rules to make sure everything is there.
I am an incredibly thorough individual, however I have made several mistakes in my job threads in the past in which I've missed some attacks, abilities, or didn't have enough magoi/stamina to use an ability. Even my C-tier jobs can run 3k+ word count.
The staff members are not just grading 1 job. There is a full site of members to grade from, spanning from abilities, weapons and item purchases all the while the staff is required to do their best in balancing these matters.
Excluding the site admin and the staff account, there have been 46 posts in 2 days this month. If we say 10 of those posts are staff posts, those other 36 posts require members of staff to review at some point in time.
That is a lot of time.
So a staff member who is reviewing these things may also need to step away from it for a moment in order to speak to a forum member and answer questions. If they forgot how many attacks happened in a thread, are they supposed to start over from the beginning?
I respect staff for the amount of work and effort they put in when they work to keep the site as balanced as they can while still trying to enjoy themselves on the site.
In short, I find the rules take minimal effort on the player's side and offers maximum overall efficiency to make up for that expended effort. I don't feel this rule needs to particularly change, unless perhaps the staff members think they no longer need it to run efficiently.
