Damn, you can't be serious.
First of all, this version isn't the free. It includes most shit.
For argument, let's see :
The SSQ are copied from whatever pack this is with a few adjustements to make it on L2J.
This is the same as L2JEuropa or Mobius
Just check for yourself, from a small part of it :
L2JSR : https://gist.github.com/Sdw-/a21b767d87112f60703a
Mobius : https://code.google.com/p/mobius-source/source/browse/trunk/dist/gameserver/data/scripts/quests/Q10295_SevenSignsSolinasTomb.java?r=546#252
It's the same for all missing L2J quests. It's SLIGHTLY rewritten, again.
Yeaaaah right. You still use the old L2J skill system with broken formula. For instance, all your glad skills use Formulas#calcPhyDam where L2J have EnergyAttack, this formula has been RCE from L2Server, and that's the very first skill in xml.
And I just spend 5 min doing this, not more, it's kinda ridiculous.
But I'm sure, you don't even have the recent features done on L2J (karma, exp penalty reduction effect, ...)
