ekhm sry for being off topic but not really that much off
I see everyone compares attack/def BPs ratio and when attack is much higher then its better...well not necessary. I gained lots of def BPs attacking lol
I know what you are thinking so let me explain
when i try to conquer a city and my CS is in the harbour then my enemy sends at me hundreds of LS and other stuff to sink it. Each time I try to conquer a RMs city I get ~5k def BPs from protecting my CS. It happened many times and only last night I gained 5.4k BPs defending my siege.
These are def BPs gained in attack
So it all depends on your opponents tactics what kind of BPs you gain - if they do nothing else but dodge, its hard to have much attacks BPs. Sometimes I wonder how many players here actually has demanding enemies and fight a lot.
Its all relevant - hard to tell who is Napoleon here and who is ... not
