Who the hell has 100 S per turn for wish without clams? If you have that kind of gem income you've already won, 20 bonus gems wont pose that much of a difference, consider it a global in a way.
Even if you're wishing for gems you need the initial 80 and 55 for every other turn. In standard games that's still about 2 turns gem income at least, if it's a bigger game, the advantage is not so big, if you're alchemising, well theoretically you're just using fire gems (probably) for wishing, but in no way in a game breaking advantage either way.
I fail to see your points?
