For some reason MMO-Champion doesn't have what official PTR notes say: Purification once again increases healing done by all water totems. now only increases healing done by Healing Stream Totem by 50% (was healing done by all Water totems).
I greyed out the old PTR note as the strike-through did not carry over on the cut and paste.

So HTT is the same as it was on previous PTR except for dps specs.
In summary, latest HTT on PTR is same as live in game for 10 mans and super buffed for 25 mans for resto.
