1) Was not there
2) In battle servers,(which those same rules apply to Strat) You can run as MUCH as you want as long as there is 1 other person fighting. As you are not delaying(since you have a teammate who is engaging and killing the guys that aren't chasing you). It is a valid, legal Battle tactic. This same tactic is allowed on strat. Even if the entire team RUNS like chickens, if 2 guys fight, then it's not delaying, regardless of anything else.
3) Common Sense: Would tell me that banning(for 1 hour too) the entire enemy team is not common sense. Period. Don't try and Hide behind this clause and rule on the delaying justification. I've clearly shown that those tactics are not against the rules. Also, if someone insists on just blocking, that's not breaking any rules. Ever heard of shields? They do the same damn thing. If someone has 13 shield skill, and 10 people whack on his shield, he doesn't have to unblock as he's fighting. Regardless of how lame it can be, it's perfectly acceptable.
Revoke the damn admins rights.
