leap of faith seems to be adding alot of depth/skill to the class which is nice to see. lets hope it can be used in shadow form from the get-go. with good coordination it should boost your team mates survival alot and hopefully it will remove snares which isnt to much to ask for.
mind spikes sounds great, shadow priest damage output in terms of spells hasnt really changed since tbc so its good to see this addition. the spell sounds abit like "pain spikes" [ http://www.wowhead.com/spell=32026 ], a spell used by some shadow outlands/northrend mobs, pain spikes has the debuff effect of reducing maximum health which is gradually returned over time to the target like a hot, hopefully something like this could be talented
i like the idea of inner will although at this point inner fire seems far superior. im hopeing it can be talented to increase movement speed up to say 20% (from 12%) especially if its low down a tree and can be included in a shadow build with improve shadowform
*snared* --> aoe fear / horrify / tailoring net --> fade (whille inner will is up, run forest!)
or maybe we get a blazing speed talent that only procs when inner will is up, possibly having anoghter proc inspiration (10% damage reduction, 15 seconds) i live in hope [Everything i say comes from a pvp point of view]
