....by fishing.

Here's the deal:

1: Get 15 people that want free honour
2: Go to AB
3: Have them all fish (or w/e) instead of capping nodes or killing
4: Opposing forces cap all nodes and win in 5 mins
5: Repeat

GMs have on several occasions confirmed, that this is NOT an exploit, as people can do what they want in BGs.

Only works during BG holidays, but with the softcap on honour, who cares! On holidays the math works out thus:

1 loss = 5min

1 loss = 600 honor (bonus)
1 loss = 150 honor (hks)
1 loss = 1 token

3 tokens = 400 honor

1 loss = 600 + 150 + 400/3 = 883.3 honour/5 mins = 10600 honour/hour
