I've filed a bug report (which has been accepted) relating to the WHM lily system in PVP, namely that the lilies get consumed by things other than abilities which refer to lilies in their tooltips. The report is here:

It's hard to test this properly because it's a pain to swap abilities out and rely on being in combat and taking damage to actually generate lilies (if only it worked on the training dummies!) so in order to get it addressed, I'd be grateful if other WHMs could add to the bug report with any other abilities they notice incorrectly consuming lilies - especially other PVP additional actions. Thanks.
