It's not so much whether we need it right this instant as a question of prioritisation. Ember-Winged Cloak is a core part of our schtick and more valuable than many other things we spend training dice on each turn, so dice should be removed from those things and transferred tomorrow valuable things. I'm not saying we stop researching Skill-Tricks, Utility Tricks, wrestling, social tricks, and so on, but we should keep it within a more manageable slice of our training dice budget. Work on a few tertiary skills at a time, not ten or twelve at a time.
Now I think we've definitely moved a lot in the right direction with making larger consolidated investments in stats and so on, so I don't want to be Mr Grumpy Pants or anything.
