I find the leaderboard ad a great deal more tolerable than the skyscraper one which seems to distorte my screen somewhat. Personally, I'm willing to keep it on. However I am a fairly new player and can see how, for those who have been playing for a long time, the ads would be more distracting and ruin the immersion. It's opt-in at the end of the day so I feel it already accomodates for everyone.
