Actually that may not be a correct assessment. The likelihood is that Ichigo has never been at the full capability of his bankai until his fight with Aizen. If thats so the natural progression would be that his bankai being that powerful would be correct. It makes him overpowered to some in the view of his opponent (Aizen) and due to other combatants but in contrast Ichigo does take upon his bankai mode far too often when it should be a last resort deal as stated numerous times by various captains. The idea that he enters into it immediately upon a fight shows his lack of skill and effective use of power. Hence why he needs some boost in power during his fight with Ulquiorra. The power level exhibited by him during his fight with Aizen is reflective of greater control and utilization of power that time and training and zanpakuto communication would bring. It should not be a state he enters lightly upon fighting an opponent. The lose of power had nothing to do with that power leap it is a reflection of a one shot technique that should not be used unless as a last resort. His power level in bankai was not what added to the defeat of Aizen so much as the final getsuga tensho. The point was him learning the technique not him gaining a greater control of his bankai. There is still room for the return of the level of control especially with the time jump leading to more maturity and understanding from the character.
