Have to agree, got the 4set tonight also - very disappointing bonus compared to the variation Guardians have in their sets. Will likely only use helm/leggings for crit defense and the rest the teal drops with crit defense (when those bloody Fornost gloves drop...) for raiding.
Tried it a few times and the heal is quite small for a 60s cool down, it either needs a considerable boost or the cool down removing to be of much use, or even if conviction gives a small mitigation buff/resets a cool down/inc heal buff, shouldn't be much of an issue removing the CD really as its not as if we spam the skill when it has 24-30s duration.
Still getting the whole set 'just because' but shame it couldn't have been a better bonus really, as it stands there isn't really any reason to use all 4 pieces considering there are better teal drops/Hytbold - would definitely prefer a scaled version of the Orthanc 4-set though (i.e. more than 600/stack and refreshable), when it was initially bugged and the incoming healing buff worked on the whole fellowship with convict was fun
Will try and test it in some groups tomorrow also.
