No, it isn't. It's taking a shot at people that aren't here to defend themselves. It's bad form.
And I've had newer players that got overwhelmed by the complexity of a level 1 fighter. Clearly, there are a variety of experiences among newer players, and WotC thinks that it's a problem often enough to warrant a change based on feedback they've gotten through the years. That isn't saying that newer players or engaging in elitism, it's recognizing a common problem and making changes to fix it.
There can be "simpler" options.
I.E. champion fighter can be 1st level subclass.
having crit on 19-20 is not really complicated.
maybe add +1 HP per level to champions HP and second wind.
Draconic sorcerer(if buffed) can be made without bonus spells and still be simpler but strong option vs aberrant mind or clockwork.
same with feats:
you can get as I mentioned; Fey/shadow touched or telekinetic for "complicated" characters and +2 HP per level for "simpler" characters.
Every class should get one sub-class that is "simpler". that is, it get more "passive" abilities than active.
extra HP, extra damage, extra AC, extra usage of already base class present abilities.
