It wont even be all that god mode, from the game footage its about a 5k per tick heal that you can use 3 ticks of per minute. Sure yes its nice I'm not saying its utterly useless or anything but when it ceases embrace disallows the cast of any other abilities by the fairy and in a typical minute is equivalent to two physick casts its kinda underwhelming. But hey its better than dissipation so I guess we should all be jumping for joy ;p
Judging by tooltips as well its an ability, not a spell, so rouse likely wont affect it either further closing the gap between it and roused embrace spam.
