Guys I would like to put this bantering into end game perspective. I am 11/12 i90 SCH "AND" WHM. I have downed t5.

Here is my input on the changes:
WHM medica II change was to remove the high enemity from the ticks. I do not see it as a nerf, and if you have to get everyone up so quickly you are better chaining medica II > medica I.
WHM Cure III is a huge buff. You guys just do not use it thats why you are hostile towards it. now with cost reduction and radius increase you need to start using it over medica II in certain fights.
SCH Lusterate buff of 5% was due to Virus only being able to be cast once a min. Sacred soil will now have to be used more often in result also.
