Hello
The newest version of monsters at server, provides an upgrade at their stats (patt/matt/pdef/mdef) and thats all.
They didnt updated at experience given everywhere, item drops (Primeval Isle), adena (Isle of Souls/Storm Isle) and also there are a small decrease at spawn rate everywhere.
You are doing very good job, the update is very good (exept monster difficulty and the cloak bug at it's release), the updated events are amazing, so i kindly ask you to keep the current update and restore the monsters at previous version.
Thank you for your time
