Some people raise the issue of "brailling" tiles and refuse to play with etched in tiles, such as those that which commonly come with a store bought version of Scrabble. Is this a big deal? Have there been issues in the past with "brailling" in top-rated tournament play? Unless if someone is super good at it, I would imagine it would be easy to see if someone is taking too long to draw their tiles. It seems like too big a fuss for me.
