It's nice but pure casters don't need that many feats: the primary metamagic feats plus maybe a couple of Spell Focus / Penetration feats. And while it's expensive, Improved Scorch adds an useful perk to a fire warlock they otherwise couldn't get. [Dragonborn warlock is another option if you'd like to add breath attacks to your combat rotation plus other caster bonuses.] Likewise pure Artificers already get 5 bonus feats (6 if you count free Rapid Reload) so they're not usually hurting for feats. The other human perks like racial Damage Boost, heal amp, etc. might be more valuable, though, so it all depends on your build.
EDIT: also while you were gone they boosted the roster of F2P races to include drow, Dragonborn, Tiefling, gnome, wood elf, half-elf, and half-orc, with Warforged as the new
400 Favor unlock replacing drow. Likewise druid, monk, and warlock are now F2P classes. So newbies have a lot more build options than they used to.
