But SR5 doesn't do the MAG split for MysAds. You get your full MAG for casting and for Adept powers (you do have to buy PP at chargen for Karma, but, well...it's still the best deal you could get). Mystic Adepts are outright bulldrek in SR5, because you only lose astral projection...and gain a full box of adept powers for 30 Karma. Spend 1 PP out of 6 on Astral Perception, voila, you can also see Astral, you just can't go into it. But you can get 12+4d6 initiative on a mage out of chargen even.
SR4 did the split between "powers MAG" and "casting MAG", which made Mystic Adepts rather useless, since 4e was, generally, better disposed towards mundanes with prices, Essence rules (you can have about 7 points of Essence in 'ware, if you balance it really well, like "4.5 cyber and 2.8 bio", because the lower of the two got treated as 1/2 Essence cost), and so on. 4e has lots of problems, but I find that it's the closest to mundane-friendly without just hitting everyone over the head with legality rules.
