I have a 5 box team with 1 paladin and 4 shamen. I did this team for a combination of PVE in instances and for PVP in BGs and Areana (in arena I would need a healer to replace the paladin).

I have noticed lately on some videos that 5x shamen teams are able to also do heroic instances and even the new instance with patch 2.4. I thought a tank was required in any lv 70 instance or heroic instance, but it seems I was wrong if you have 5 shamen.

So I am considering going with a 5th shamen and forgetting the paladin. What are your thoughts on this? can a 5x shamen team do everything that a 1x paladin and 4x shamen team do?
