hey i posted this in my forum so thought i'd throw it in here.  might help motivate some bankers back into life. 

*Making cash - This means looking always to make more, build to 25%, 50%, 100%  Bankers should not become stale, always keep pumping those planets up!
*Having good research - Building some rc early on to make building cheaper, funding 4 ticks a day later (especially when you start replacing rc with Tax Offices)
*Defending yourselves - consistantly updating laser amounts, every other day up by 1 or 2 per p.  More ground is now needed, attackers can wipe through a bankers ground much quicker.  Semi decent amount of figs will deter bankers sending tickers, however do keep some stationed for backup.
*Agents/Wizz - Agents is common sense, if your 150k nw, have 10k agents, always have enough wizz for SA
*Retakes - you cant attack anymore, so do retakes or offer to take planets of attackers, or send to planets won through diplomacy.
*Upkeep - not the banks job to pay upkeep.  tut tut, thats your job!
*Food - not the banks job to supply your food.
*Opps - you have 24 opps a day, make use of them.
*Bargain Hunt - keep your eyes on the market for good deals, if you see 20k iron on at 10, buy it and sell it for 15 later.
*Portal - When instructed make 1 a day, +1 each day until your making 8 a day.
*Ressies? - bankers can make the odd little resource, this can be useful for making expos, building portals, lasers and replacing lost agents instead of adding more demand on bank.
*Send to your lost planets for when the attacker retakes

meh, hope this helps a little
