WAR in BC. Do we need it?

[Tronic]

So WARS are viable is just that healers are lazy?

WARs are a worse tanking class than PLDs in end content. So if beating encounter X requires a Y level of gearing for a PLD and healers, and you take a WAR, you need to compensate by having a WAR with Y+1 gearing, or having healers with Y+1 gearing. There's no free lunch, and the WAR entree is more expensive.
