Evasion:
In PNP Dungeons and Dragons the Evasion feat doesn't care what kind of armor you are wearing--you still get to make your evasion check if you are in full plate with a tower shield, the balancing factor being the maximum dexterity bonus allowed from these cumbersome armor types severely reduces your saves. The penalties to evasion were ALREADY built into the game! (Note that the Insightful Reflexes feat would not be affected by max dexterity bonus, because you're not evading with instinct and fast movement anymore: you are predicting what is going to happen and avoiding it, and it lends itself to being superior to the base evasion feat with dexterity because, well, you're using TWO feats and SHOULD get some benefit!)
Scroll Rarity:
Shouldn't be a thing anymore. All scrolls should be available somewhere. With all the Epic and Legendary NPCs wandering around now, there'd be a MARKET for it. Sure, level 8 and 9 spells might be much more expensive in scroll form, but they should STILL be available.
Evil Alignments:
As the world has become more inclusive, the game should also be more inclusive. Allow players to be evil and choose evil deities and powers. Let the players figure out why they'd help the Eladrin as evil players. The motivation to do so is up to them. Just let it happen already.
Missing Feats:
Still Spell (no ASF for affected Somantic spells)
Durable (+1 CON; double CON bonus HP/level--this is what toughness SHOULD be--epic CON should be DOUBLE this.)
Prodigy: Skill (one cross-class skill becomes NOT cross-class. Basically, for every point you spend in the selected ability you'd get one full rank instead of half--it doesn't give you more skill points to spend at level, and if you spec out of the Feat, the game would just convert the points back to the .5 per level they were previous--no big deal)
Crusher, Piercer, or Slasher: Critical hit damage with the said weapon type(s) is(are) lucky.
