Well i don\'t really like the idea in general but i\'ll put in my two cents. What if some monsters (generally stronger monsters) were to have evolutionary stages? I know it sounds a bit corny, but you see, if a monster were to gain EXP it could change in appearance and become stronger after it lvls. Then it could venture off to another area. After it evolves again it could move to the next before it couldn\'t get any stronger.
Monster Stage one= (^.^)
HP=50 Def=3 MINATK=3 MAXATK=5 Kills_Till_Next_LVL=7
Monster Stage two= (*VV*)
HP=75 Def=9 MINATK=9 MAXATK=14 Kills_Till_Next_LVL=7
Monster Stage three=<{*VOV*}>
HP=125 Def=17 MINATK=19 MAXATK=25 Kills_Till_Next_LVL=null
Each time the monster lvls it would move further away from it\'s original area. Maybe in a noobie area u\'d see a monster called blob who is just a regular blob. When Blob Lvls he could turn into spike, who could be a regular blob with a turtle shell and spikes on it. After Spike lvls he could turn into Tyrant, which he would have legs arms with spikes and a crowbar. (just an example)
Just an Idea...
