All these so-called OP builds are based on these two features/glitches that are not really supposed to happen in this game:
1) Damage modifiers are supposed to apply only to one underlying attack. But in this game, they may act as standalone sources of damage => thereby turning one attack into multiple attacks with every one of such attacks carrying a full set of damage modifiers.
==> This is how certain monks, certain paladins and certain throwers become OP, because each of their attacks act as if it were two or more attacks merged into a single mighty strike.
2) The Extra Attack feat may not stack on top of each other. But in this game, it may get applied where it should not => thereby granting up to 2 free extra attacks for every weapon action.
==> This is how certain warlocks became OP, because they got the equivalent of the Improved Extra Attack feat, which is supposed to be a fighter-exclusive feat.
3) A special case: Haste + Extra Attack should not stack on top of each other. Haste is supposed to enable just one extra attack, be a weapon attack or a spell attack. But in this game, until recently, Haste grants a full action, enabling the (Improved) Extra Attack feat to stack on top of it. Logically, if the Extra Attack feat applies to every extra attack, then whenever we get another extra attack, we should always get yet another extra attack, meaning: a single attack will initiate an unlimited number of another extra attacks. Fortunately, the game stops at up to 3 attacks per action.
All the above boils down to one thing: all these OP builds, especially when they are also under the effect of Haste, make many more (hidden) attacks in combat than they are supposed to.
PS - as you can see, OP => broken: a broken build is not necessarily OP, but an OP build is almost always a broken one. And here, "broken" refers to the fact/practice that these builds (implicitly) take advantage of certain features (glitches) that make this game combat-wise unbalanced (though the players using these builds may or may not be aware of that).
