It's fortunate that Wizards of the Coast can't keep it in their metaphorical pants and keeps trying to go for all of the money in the most obnoxiously predatory ways and has done so since at least 4th edition and its attempt at a virtual tabletop monopoly and "blind bag" miniature peddling.
I need to train myself to stop saying "D&D" for tabletop fantasy games because I am not going back again. I left before, and this time it's permanent. Fuck WOTC. 
I've only played 3/3.5e and earlier. Other systems of course but i never liked the changes after 3.5 and we had all the books already
IMO DnD peaked at 4e. I liked how many options there were.
