I pretty much have most of the gear listed above but my gear score is only in the mid 4k, highest I think is at 4558 I think being my healer.
I do have a decent main hand weapon on my tank but my dps all have titansteel blade (spell one) for my casters and Nesingway 4000 for my hunter.
With the warlock trinket, is Sundial of the Exile worth getting instead of the trinket which is 128 intellect and use for 500 spellpower? I would need to convert some badges to get emblems of heroism and so have not tried the sundial trinket. Having said that, using the non triumph badges I would think will drop my gearscore even lower
