Adept Powers: When the schedule for expected numbers got changed all around in SR4, Adepts apparently did not get the memo, in many cases keeping absolute costs as holdovers from books written in 1990. Some of those are not especially reasonable in the current environment (where, for example, an Adept does not get 6 power points for free).
Improved Ability This power should cost just .25 points regardless of the type of skill.
Improved Physical Attribute This is way too expensive. Sure it doesn't cost Essence, but it may as well, and having it cost more than the cheap and Essence unfriendly ware is off the hook. It should cost only .5/level. Even then it's pretty sketchy compared to the actual high end ware like delta grade Muscle Toner (.4 Essence for +4 to a physical attribute). But at least it doesn't come up on a blood test.
Natural Immunity This ability is incredibly unattractive, a victim of the current power rules. Every level should reduce the power by one rather than increasing the resistance dicepool by one.
Pain Resistance: Damage penalties are a lot less exciting than they used to be, as they no longer modify target numbers. Paying 1.5 Power Points for a conditional +1 die is just silly. Pain Resistance should reduce damage modifiers rather than altering the number of effective damage boxes you've sustained. So a character with Rating 2 Pain Resistance should be able to sustain 6 boxes of damage with no penalty.
Distance Strike I happen to know that the authors were way too cautious on this one. This is a game where people have guns, the ability to punch someone from across the room is kin of assumed. 2 Power Points is completely absurd, and was unfortunately deliberately chosen to screw people who wanted this power for thematic reasons. It should cost .5 Power Points, and it's really not that exciting even then.
Elemental Strike There is absolutely no reason to keep people from combining this with distance strike, that was just simple asshattery.
Gliding This costs too much, an should be reduced to a .5 power.
Iron Guts No idea why this happened when Natural Immunity exists. The new version costs .5 and gives the character straight Immunity to Ingested Toxins.
Iron Lungs 30 seconds is physically impressive for a normal human mortal, but seriously this is a world with compressed air tanks an Oxygenate spells. The new version costs .5 Power Points and straight up lets the adept get by without breathing at all.
Quick Draw This power straight up does not exist. People can just do this in Shadowrun 4th edition, there is no reason for a power to even exist.
Traceless Walk This costs too much and should be reduced to a .5 power.
Wall Running This costs too much and should be reduced to a .5 power.
