But it will break the balance because you can use credits at 11 59 pm and 12 01 the next day to buy some expensive research without giving a chance to the others to steal your money
of course,this is an opinion of a spammer without war income
true, but it evens out the advantage because right now the way the credits are set up, the guys who are most free to stay online longest will gain a distinct advantage over those who log-on now and then.
anyway, if anyone does what you have said, it still is the same--they have used their credits twice in 48 hours. so, it will even out because they can't use for 23 hrs and 59s; they can be attacked then.
