I play a fair amount of alternate shot, which I'm sure you know has its share of problems, especially in setting up a game. My issue, however, is about green speeds. In the last few months, there have been a lot more legends and tour legends playing alternate shot. Legends and Tour Legends always putt at green speeds 12 or 13, so when they play alternate shot, they need make no adjustments to their putting - they putt at that speed 100% of the time. This puts those of us who are not Legends or Tour Legends at a disadvantage on the greens in alternate shot, since most of us putt at these speeds less frequently. And please don't say this makes up for the disadvantage they have driving from the back tees - I would gladly tee off from the back tees if I didn't have to putt at 12 or 13 green speeds.
I have noticed that many players are starting to decline Legends when they start to join a game, so clearly I'm not the only one who feels this way. So far, I haven't done this myself because it's unfair to the player being declined, and it adds extra complications to getting started. This may change, however, because I'm getting tired of being constantly at a disadvantage. My suggestion is to make the green speed for alternate shot the same for all players (say green speed 11). Another (even better) possibility would be to allow the player who starts the game to set the upper limit for participating players, so that, for example, a game could be selected with Pros, Tour Pros, Masters, and Tour Masters only.
If some effort isn't made in this regard reasonably soon, I will have two options - stop playing alternate shot (more than 50% of my play, and I do pay for my balls), or just declining Legends and Tour Legends whenever I play. I don't like either option, but I also don't like the status quo. A little fairness might be in order.
