How many?
If the pack is so good, with everything reworked, then why is your title 'pvp' pack?
Regarding esios, we both remember what happened in marketplace section with 'new interlude packs' after he added the first unique feature.. If you were in his position, watching others making tons of money from your work, you would do the same and you can't deny it.
Absolutepower learned from l2j, which means he lacks of performance knowledge, he is not in the position to use new java features until someone uses it first in l2j and he will always avoid to 'touch' more advanced code(simplest example, features that use reflection/annotations). And i bet the 'reworks' he's done are checks/re-organization of code(which doesn't mean the new structure is always better than the old one).
@Absolutepower, you can't use 'world region rework' as a reason for selling a 'pvp' pack 80 euros.
Peace.
