This was far more informative then the,other articals and blog posts lately and has reexcited my interest in 5e.
The wizard disciple feats and wizard mark feats idea sounds awesome.
Here is my thinking Wizards will be divided into the normal specialist schools and generalists, with specialty wizards getting feature according to school with generalists getting free wizard mark feats.
I don't know which class gets the magical feats as the whole class feature thing, but if it is warlock then I suspect that they'll be feat chains based around pacts and pact specific features as well that buff feat powers.
Cleric's will be mostly spells based, but with the option of domain feats akin to Wizard Marks.
Priests will be mostly domain feats based with with a main domain that grant unique advantages, like arcana that grants wizard marks, war that grants combat manuevers, life which grants a bonus to healing, ect...
Combat Manuevers maybe feat based as well.
Druids I see remaining primal in nature, with a spirit feata based system, but still primarily vancian based, plus features. Rangers will have,the option of taking spirit feats as well, but no spells.
Paladin's I see primarily feature based, depend on,your choice of vice or virtue aedu style, but possibly with option of taking domain feats.
Assassins and Rogues, Rogues I can see picking,from a bag of tricks, which includes backstab and sneak attack as well as none combat stuff and Assassins shadow magic feats and poison abilities amoung other things, with maybe its own choice of tricks and maybe assassin guild feature.
