Issei with AxA will access to the powers of his dragon god body but it will take time to learn, train and adapt to his new powers. AxA unlike the other power up won't be just a mode on the boosted gear unlike the others its the true power of his new body,  He will have new physical abilities that will pop up that will have to learn about and control which will hider him from using the full power of AxA at first.
