Personally, I am sad about this. Serious scrabble play is largely about rack management - i.e. trying to get a set of tiles that you can play all at once for a 50 point bonus (bingo). That means dumping tiles that make it harder to score a bingo (duplicates, difficult letters) while taking into consideration the likelihood of drawing better tiles given what's been played and what letters your opponent is dumping (signalling what's in their rack). Most turns are about maximizing the points from non-bingos while putting together a good rack, and that frequently means playing words parallel to what's already on the board to double-up on a premium tile.

The 2006 OSPD addition of "ZA" and "QI" really changed the game, and not in a good way. Q-sticks (sticking your opponent with an unplayable Q) were a staple of end-game play, especially but are now basically obsolete.

OK rankles especially as an initialism. There will be (very nerdy) riots if a 2 letter 'V' word is ever added.
