early stages of a tourney,should you limp in with good/great hands

[Noodles]

just been playing bodogs 100K,
ok in the early stages is thre any point stealing blinds,?

i was doing it in the 1st few levels and thought "what is the point all im doing is stealing 30-60 in chips,whats the point?" also if you are called it is usually by something that beats you and you have to get lucky on the flop

also in early rounds i feel the only way to accumalate chips is post flop,stealing is a waste,so why not limp in with AK-ATs and big pairs? if you are reraised later you can take a call?

or is this idea daft?

was just in the bodog 100K, just before the hr break, had 1400, so i limp UTG+1 with AKs, next guy goes allin for 3000,now the blinds are 40-80 i think
should i go allin with him?

why does someone go allin for 3000 when blinds are so small?

i mean if someone has a real good hand at that stage ,then why not just raise a good bit?

what should i have done?
