Not sure what is bigger problem, this or people constantly using speed hax in siege...
Last night had rogue run from mid B (our right) to B tower and back killing everything in path without any slowdowns.
Silly person, this is not a "speed hack". I've been known to use a macro that combines Mad Rush+30, Spellweaver, and the housekeeper Godspeed pot (when my stingy housekeepers see fit to give me any). Toss in the Herald's Thunder Force, if it's up. It's certainly *not* an unknown skill/pot combination and is in no way a "hack" or exploit.
I've run down and killed toons on Rune Disks+30% mount pot+castle mount buff that have broken past the middle area and were heading towards our castle tower(s). The first time some of my guildies saw me zoom past them (I'd color-shifted to "plaid"

), they were astounded.
As a P/S, there are only two classes that I cannot outrun *on foot* if they're using a similar macro. You're welcome to take guesses as to which classes those are.
