Yes and no - I think some are hung up too much on particular role-fits for particular role-designations to see anything else. Where carriers in the X-series are concerned - they have always been a form of warship and not really along the lines of current generation real world fleet carriers that some seem to want them to be,
The current (2.2x and prior) role fit for carriers is not what some would like them to be and I respect that even if I disagree with it. What Egosoft are apparently adding in 2.50 is a resupply feature - not tried the Beta so not sure how it works but from the sounds of things the dedicated supply ships will notionally do a better job of resupplying ships. While I do not feel such a feature is necessary and would rather ES had concentrated on other things what is done is done.
Removing the high-way ring would achieve little or nothing and may in fact make matters worse, the fundamental issue is not the highway ring but rather the trans-sector routing algorithms for all ships. It is not an insurmountable issue either.
I believe it is almost universally agreed - other minutia aside - that the AI aspects are still in need of work, whether any AI changes introduced in 2.50 are going to be enouver to address that is questionable.
