Common situation in MP

This is definitely raise or fold. If you feel that raising will often just get the hand 3 to 4 handed out of position with little fold equity on the flop, folding is fine.

If the table is loose/passive what is wrong with limping here. If you can't get everyone to fold for two bets, but can get everyone to call for one bet. Sounds like the perfect situation for a set hand.
