When it came out, the thri-kreen was very popular for all kind of crazy rogue builds in order to abuse it's multiple natural attacks, but eventually, the RHD and LA made it forgotten.
Anyway, did you know the Thri-Kreen is CR1? No? Forget kobolds, the EXPH thri-kren has a freaking 5 natural attacks, good stats, HP and several tricks all around!
In order to make it a lv1 class, you don't get any ability score or natural armor bonus. You get all 5 natural attacks. Weak saves and skills make room for the PLAs and the poison which got nerfed.The number of uses increases slowly with level.
The jump bonus starts weaker, but eventually becomes much stronger than the original monster.
Like the original, rogues and any class with fixed bonus to damage will be specially useful for the thri-kreen
