"As long as you kept taking your bonus at 23:50 you'd still get as many bonuses as everyone else. The real flaw is as you say, playing delayed. Then you wait and don't play until your building cost or expenses are way down."

decrease the time you can hold bonus points before losing them, on the express server, and you solve this, no? if we moderately increase strength, it would make sense to moderately decrease time being able to hold them? (before losing them?)
