Not sure about all the other servers but on mine the EPl towers are rarely camped or people never even bother with them.
PVE servers are the best to do this on but it can be done on a PVP also.
1) The thing to do is cap a tower but only just enough to get the honor (189) not the whole way accross the bar.
2) Have a friend on the oposite faction then go and move the bar back to Neutral (or back to his faction if you both want honor, this method will take a little longer) then start from step 1 again.
It takes 8 seconds for the bar to move from 1 bit from your faction to Neutral then 8 seconds to move back to get the honor surge so 189 honor every 16 seconds or so.
