There is such a thing as having too much of something which is what we are getting. People want more but they want something different.
Meh. If you don't want anymore sub-classes, fine, stop paying attention to them, don't use 'em. I can see being disappointed at the lack of something you still want, but not angered at the surfeit of things others' want.
How many scouts do we really need?
Ranger-as-scout has baggage: it's a nature-oriented caster. Fighter-as-scout has issues, too, it's a tough-DPR frontliner. Rogue-as-scout has the inverse issue as the fighter. Depending on what sort of 'scout' you want - magicky nature dude stalking about, badass stalking about, expert stalking about - yeah, several might be called for. Then there's feats and backgrounds.
The advantage mechanic is inherently limited as once you have it, it doesn't stack.
Which is elegant, in a way.
With Bounded Accuracy you can't hand out many numerical bonuses or you break the system.
At least not many stacking bonuses. Sure.
5E is a more limited system than even 4E in my opinion due to its core mechanical design.
Not a very meaningful comparison. RPGs, by their very nature, aren't too terribly limited, 4e certainly not standing out for being particularly more so than usual, even less so, by D&D standards (D&D's traditions like class/level, Vancian magic, and the like /are/ somewhat limiting). 5e may be back to a more traditional presentation of classes and smaller numbers (when it comes to d20 modifiers), but it subverts that do a degree. Hps/damage scale rapidly, so there's room for advancement & modifiers in spite of BA. Classes are back to locking concepts down with mechanics, but there's lots of sub-classes and independently-chosen, customizeable backgrounds to round characters out. And there are 'modular' options the DM can opt into or out of. Every new option that comes out is just that, optional - bloat only happens if the DM bloats his campaign, if he picks and chooses options, no bloat.
And, most of all, 5e, like the classic game, is very open to being modded, making it, ultimately, completely unlimited, even when it hasn't got that much material out yet.
