The 'classic' argument is simply this:

The weapons from VP are a big boost over what drops in kunark (especially once the BOBDE stopped dropping)...

However, the second epics come out, the real worth of most VP weapons goes completely kaput outside of gearing up alts who aren't getting epics anytime soon.

And if you consider the keying process, it's not as feasible to key your alts as it would to say, sebillis or howling stones.

So a major part of the zone's reward system would be essentially wasted if there wasn't proper spacing between VP coming out and epics being introduced.
