Nice analysis!

Problems with most MMOs:-don’t feature a variety of basic attacks/spells.-don’t feature mini-combos or mixing basic attacks with skills/specials/passives/itemization (or other systems).-few skills per class, on top of that grant ALL the skills, no choosing/branching/specialization needed.-rotations where a setup is 90% of the time better than others, everyone goes same skills, same rotation.Again its trends to CARBON COPY.
I don’t know of a game that does good in here, all above problems considered.(Path of Exile would be an example of what NOT TO DO, since its basically choose a skill and spam it until your eyes burn.)
[/quote]I think Blade & Soul could be put as an example?
Even tho all skills get unlocked for you at max level, you have some points to alocate and upgrade internal “trees” most skills have (yeah, each skill has its own tree). You can’t upgrade more than one branch inside a tree and can’t upgrade a full tree for every skill you have.
This upgrades can give more damage, resource management, buffs. debuffs or change the skill completely. This changes your combos, since some skills need the enemy to be stunned, knocked, choked, on air or something else to be used.
Some skills need you to be on those conditions to be used and they act as counters/releasers. This way, on PvP mostly, there isn’t a faceroll rotation to mindlessly perform.
I think they do a good enough job with equipments (chose your weapon and accessories from 3~ of your level range; body slot changes your outfit and doesn’t have stats). But class paths are locked and even for some races only. 
Also, I don’t like Diablo 3 for that spot. It could be before, but now you either have a set or you are useless. Kanai’s Cube is only a false solution for the problem, making normal legendaries less dead, but you still need sets to do well…
But yeah, they still have a big pool to “chose” from.
