Buying an expansion does actually do that.
How can you say that improvements in stats beyond anything that the prior expansion can grant is not player power.
Can a player limited to content from the base game gain the same stats that one with the Burning Crusade expansion is able to ?
Can they compete on equal terms ?
No.
That is player power, by your own definition of the gear from a boost providing that same thing.
It does not stand.
You keep repeating the same flawed statement over and over again.
And keep making a fool of yourself in the process.
You cannot say that gear gained from a boost is player power, while that from an increased level cap and increased content accessibility is not.
You lost the argument, because of the constant refusal to do anything but repeating the same thing.
You keep saying that I am repeating, but I have presented this as another argument.
