Ya know, rules, are there for a reason, where a marshal, could use it at his/her disposal to prosecute an action.
However, whether to prosecute the team or not, is entirely at the discretion of the marshal.
Of course, we don't do every thing black & white. Its like the football games. You follow every single rule in the book, the game gets kinda boring, like the infamous 30-cards-in-a-worldcup-match thingy. Sometimes we'll turn a blind-eye to some stuffs in order to ensure a smooth game. However, I believe only experienced marshals can execute this properly, with DotA still relatively a fresh face in the gaming scene hopefully as time passes by this situation will improve. Of course, constructive feedbacks and suggestions are always welcomed to enhance such processes.
Personally, I believe there are certain loopholes in the WCG R&R that needs to be mended. I believe al your suggestions here will be taken into consideration as many people are indeed reading these very threads in lowyat.NET. However, please keep post counts to a minimal and only post constructively, reading repetitive posts does make the reader sleepy ya know.

My 2 cents:
1) Backdoor should still be banned, its absolute for me
2) Warding should also be banned. By delaying the spawns of neutral creeps or halting it, the opponents gets less chances to farm. I believe this would be a more dire issue than Chen's, as in my experience, he and his cronies are not much of a concern in 6.32b anyway.
3) This rule is indeed weird as in a 60 mins game. There'll rarely be a situation where both sides are down to 1 rax and both are racing for mega creeps.
Perhaps, there might be one last modification just before WCG National Finals. Maybe if you guys send enough (proper) emails to In2, that's a maybe though

I've received called from few gamers and heard from few gamers on the spot about their opinion on the rules.
Because there's so much prelim around the nation, not only we can't standardise rules for different tournament. Now even rules among wcg marshal is not standardise, that's why I called up a meeting. WCG Marshals dun hate me =P, make u guys work 1 more day but i think this meeting is needed.
So gamers who got something to say bout the rules, please post here. I'll take down your points and discuss on the marshal meeting tomorrow.
