If I had to propose something, I'd say that shifting a little of the FT training to JS training would make things a little more reasonable. We'd still have FT training, but maybe temper the pops by, say 10%, and shift that little bit of training over to JS. That would mean (for a 19-year-old) that for FT training, FT would pop typically with 2 weeks of training (not that different than now) with maybe a pop here or there taking 3 weeks, and with JS training FT would pop in about, say, 8 weeks (sort of like with JR, HA and DR do with JS training now). Surely, if FT are a separate skill, that skill is more affected by JS training than DR and HA!
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
