This is what I use on my warden. There probably tweaks that can be done to it but it holds up well even in raiding. https://u.eq2wire.com/soe/aas/884764236505
The first one you linked is missing quite a few useful AA. I've also found that left-side prestige performs better for healing AND dps this expansion if you spec into the damage sheild. The ward is sizable enough to make a difference, it's got a HoT attached, so automatic bleedthrough coverage and the damage shield hits hard enough to matter. You can easily keep Clearwater up on 3 people while doing other heals and dps. This is the one I use for groups and raids https://u.eq2wire.com/soe/aas/455267281748
