Steeliest of the dragons
And this needs repeating, just for universal truth. Welcome back!
No, your disequilibrium is because missed 3.x/Pathfinder, that was the height of the player-empowerment, builds, RAW (Rules As Written) obsession and optimization.
Of course, you can optimize in any game, (people even did in 2e and earlier, just not so formally and with fewer tools, with 'gaming the DM' perhaps being the most critical form of powergaming), and people did bring that 3.x mentality forward into Pathfinder (which embraced it), 4e (in spite of it being fairly well-balanced), and 5e (in spite of it's more classic-D&D style).
Anyway, if you ignore the naysayers, you should find returning to D&D with 5e after last enjoying 2e an easy, comfortable, and rewarding transition. Welcome back, and enjoy your D&D.![]()
