It's pretty straightforward now: If the ability requires stamina, it scales off stamina, weapon power, and weapon crit. All tooltips say, "Deals xxxx magicka damage," or, "deaks xxxx physical damage." All the cost & range information is already there in the top right-hand corner. The champion point tooltips explain what damage types and stats it affects, and putting this info on the skill tooltip would be superfluous. Most of the information that you're asking for is already there, and the rest just requires just a small amount of thought about the game's mechanics.

For blade expert it says "increases the damage of light and heavy attacks ...". I can't see what clarification you need, it increases the damage of light attacks (left click) and heavy attacks (hold your left mous button) and doesn't effect any skills.

There are cross resource effects, but they are allready explained in the tooltip.

I can't blame you for being confused, @Jar_Ek. This game has had difficulty with mechanics and tooltips from the get-go. Back before patch 1.6, all class spells used magicka & spell damage, and all weapon skills used stamina and weapon damage. However, anything within melee range used weapon crit, and anything outside of that used spellcrit. It has never been clear how damage and resistances are calculated. Some buffs/bonuses appear to be additive while others appear to be multiplicative even though the wording of their tooltips is identical. When something doesn't add up, I hear players ask, "Is the tooltip showing the correct values?" Even 1+ year after launch, figuring anything out still requires some degree of guesswork because the API of this game is so obscured.

Perhaps your reading comprehension does need a little work, but this thread touches on a larger issue:
The inconsistent and oftentimes bugged tooltips, passives, and abilities still need alotta work.

No, the tooltips are blatantly wrong in a number of cases. See fossilize, sea of flames, and empowering chains. Plus they don't reflect the impact of champion points AT ALL.
