"Bound Weapons deal more damage"
That's great, how much more damage?
"Greater duration for reanimated undead"
.....how much more duration?
"Calm spells now work on higher level opponents. Cumulative with Kindred Mage and Animage."
Awesome, but how many levels higher? How do I even tell what level an opponent is?
Considering for console players, that can't conveniently alt tab and google this stuff, and also can't even remove perks, so much lack of information is pretty lame. These aren't exceptions either, there are many more perks that just don't tell you what you're actually getting.
The third example is especially bad, since you don't even know when your spell will work and when it won't. Considering calm spells cost a fair amount of magicka, and if they fail will alert enemies to your presence.....it's not so great.
I don't think I need to explain too much why this is just bad design.
