1. Freedom to leveling
Sometimes u want to kill cute mobs like poring, mystcase, poporing, lunatic (ragnarok online mobs)
sometimes u want to kill undead like zombies
sometime u want to kill bandits types
sometimes u want to kill orcs, centaur type
I want this mobs exist in all level stages. example there is level 1 poring and also level 100 poring king world boss
there is level 1 centaur (like gw2 starting zone) and level 100 centaur king that as strong as world boss
u get the picture? however the map is very geologically correct. Meaning, If u travel from town to town, the mobs design appear logical.
2. Maps systems.
level 1-10 players share the same map. the map is huge, imagine gw2. In this map there is level 10 boss monster that player who level 1-10 can join force to defeat it.
There are also level 100 world boss, so max level player can come back to the map and kill. For reason like loot, cool buff items (with 0.1% chance drop) and job progressions, some job require u to kill world boss before u can increase rank. however, lower level players cant do much damage
mini boss spawn every 1 hours and world boss every 3 hours.
