Of course, a rakshasa in a party of ECL 15, say (in otherwords, enough to take 1 class level) will encounter and engage opponents of upto EL 19.
So an Ancient White dragon (to pick another D&D staple) of CR 18 should certainly not be overpowering, right? Except... even without any magic items this thing has 375 hp, an SR of 24 (meaning our rakshasa7/sorc1 will only succeed on the caster level checks 1/4 of the time), nice things like a breath weapon dealing 10d6 damage, and a base attack of +30 (and a strength of 33). So yeah.. you have damage reduction, and let's hope that the dragon can't Align Fang that away, but even so, you've got a problem... And just to top it off, the dragon's caster level is 9th and yours is 8th

Rakshasas are one of the better choices for high levels, but still... a level adjustment of +7 is painful. You can do it for flavor, and because of the great Con and Racial HD, and damage reduction and SR, you'll survive quite a while, but your attacks are truly wimpy for such a character. Being an 8th level sorcerer when you could be a 15th level sorcerer, is a big, big issue.
And we all know that if you want to be a sorcerer with level adjustment, you want to be a...
pixie
Ahh... how cute... and how permanently invisible, an SR of only 2 lower, 3 less LA, A damage reduction which, though only 10, is /cold iron (which isn't very common in monsters, and isn't easy to come by either), and a fly speed! It's also one of the few LA which is equal to CR.
