Is there even a point to raising level caps?

[PikachuLink]

pretty much all mmorpgs ive ever played have increased the level caps thats what i mean by normal. and the ones who are setting their cap have already raised their levels high enough that it would just start getting rediculous but they did raise them to higher levels. everyone wants to reach higher ranks it makes them feel better. and its like OH YEAH! i get to rank up again im so bored of staying 50! i get to level up my job again woot! people get excited about that people dont get excited as much about only system changes.
