The verses worldly Andre mentioned are not in the Nestle Aland new testament so there are legitimate reasons thwey are missing from the NWT. However Atlantis mentined a lot of great points where the NWT has messed with the original scripture. I 'd like to add two:
NIVLuke 23:43 Jesus answered him, "I tell you the truth, today you will be with me in paradise."
NWT Luke 23:43 And he said to him"Truly I tell you today, you will be with me in paradise"
With a comma placement they manage to postpone paradise by a few thousand years- even though there are no commas in the original manuscripts!!!
NIV John 3:16 "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
NWT John 3:16For god loved the world so much that he gave his only-begotten son in order that everyone exercising faith in him might not be destryed but have everlasting life.
Turning simple faith to a complicated religious experience. How do I get saved? Well first you begin with a bible study and if we deem you worthy you could go door to door............

The Greek phrase for "I am" is ego eimi. Here eimi is in the
present tense. However, in Greek, as in many languages such as French, a
present tense is often used as a past tense. For example, a French speaker
might want to say:
"I went there ten years ago."
He would say:
"Je suis alle la il y a dix ans."
Literally:
"I am gone there it there has ten years."
The word for "am" is "suis" and is in the present tense. But by standard
usage, the past tense is almost always rendered by two constructions that
are something like "I am gone" or "I have gone" in English
I do not know french however in the greek you cannot translate a present tense as a past tense.It is a clear quotation of the septuagint who had god say " i am" at the burning bush. Why would they try to stone him instead of dismissing him as a lunatic?
57 "You are not yet fifty years old," the Jews said to him, "and you have seen Abraham!" 58 "I tell you the truth," Jesus answered, "before Abraham was born, I am!" 59 At this, they picked up stones to stone him, but Jesus hid himself, slipping away from the temple grounds.
