Thank you very muchSorry, I forgot to answer this, yep, that's fine.
Power: You can replace a power with another power of the same type (at-will attack power, encounter attack power, daily attack power, or utility power), of the same level or lower, and from the same class—a 5th-level attack power for another 5th-level attack power, for example, or a 22nd-level utility power for a different 22nd-level utility power.
You can’t replace a power that’s a class feature (such as a cleric’s healing word or a warlock’s eldritch blast) or a power gained from a paragon path or epic destiny.
Did you hoseruled this?
PHB p 28 ('Retraining')
I looked at the other fighters sheet to avoid doubling to much powers. Our fighting styles should look different.
So, I end with the same 3rd level power twice or a 3rd and a 1st level power?
This nearly forces you to double up, as 3rd level powers are usually much better than 1st level ones. I will re-check my sheet.
Thanks for the answer. Everything is clear now.
