People go the 5x shammies for a reason. They do awesome dps when stacked, they can heal (multiple targets), they wear mail and shields to take less physical dps, they get mana back from being hit, 5 shammies can bring a huge array of totems to the table, you get a tanking elemental, a dps elemental, a huge speed buff spell (bloodlust/heroism), able to negate spells (grounding totems) and fear (tremor totem) and can hit multiple targets (chain lightning).

Very fun class to play, good at both offensive and defensive styles of play, I highly recommend the shammies to start off with.

PS: If you live near Australia, or play around our times, roll on Frostmourne. There are 5 very active boxers there (2 on ally, 3 on horde) and Opt is ally too but he went to dual boxing. You are more than welcome to join Tasty and I in our guild...<Gold Farmers PTY LTD> Alliance side.

Frostmourne is becoming the official multiboxing oceanic server, well, to tasty and I it is anyway lol :P
