The level is a number. It is neither awesome or bad. If you find it too easy to reach level 99 then make the game harder with many of the tools available. And I don't mean make harder just by raising stats, that's the way a game like Final Fantasy XII would do it. Change AI of enemies, make a game where you have to think.
There is an unhealthy obsession around these parts with "big numbers". Break HP, Break damage limit, break level, more ap, more battle points, more experience, more HP for enemy.
They are all numbers. Understand that. There is nothing good or bad about a number. Nothing intellectually stimulating or clever. Good game design can work with HP limits of 1000 or HP limits of 10000000. It can work with numbers or health bars. This idea that numbers are important is in your mind. Good game design exists based on content and quality of the game itself.
An enemy isn't amazing because it has super quadzillion HP (See that brainless joke called Final Fantasy XII), nor is it cool that you get "level 255" or "99999 HP". Realise this, people.
End rant.
Edit.
Although, saying that... level 100 does look better than 99... so from aesthetic pov, I understand it.
