4 pallys 1 druid

What do you think about 2 shamans and 3 warriors ?
And if you think it is viable. Should I go with 1 shaman and 4 warriors or 2 shamans and 3 warriors ?

For PvE and doing dungeons it will be great. You'll cleave through mobs super fast with warriors and windfury totem. Less optimal for PvP (IMO) because shamans have no way to dispel slows/roots so you'll be kited fairly easily.

Whether you want 2/3 or 1/4 is just a matter of preference. You'll do fine in PvE either way. The advantage to having 2 healers in PvP is being able to cross heal if one of your shamans gets CC'd. Your dungeon clear times will be slightly slower with 1 less DPS but you'll also be able to push faster. 2 Healers spamming downranked chain heal on 3 warriors should allow you to just go ham (within reason.)

/cast [target=mouseover,help,exists] [help] [target=targettarget, help, exists] Chain Heal(Rank 1)

Should work fairly well. 99% Of the time you'll be able to get away with just spamming r1 chain heal on the mobs target. If you need to heal another character, just mouseover with a repeater region on your unit frame.

Having a mana tide totem every 2.5 minutes is also pretty nice.
