Where the glyphs are right now, the one to an army's right is 7 walking/5 flying spaces away, while the one to the left is 12 walking/10 flying spaces away. That means that for many armies they will be 2 turns and 3 turns (walking, 1 or 2 flying) away, respectively. This makes it much easier for most armies to claim/hold/attack figures on the glyph to their right. And if the glyphs come up something like Valda+Lodin, whoever is closer to the Move glyph will have a distinct advantage.
If you add tiles to where the green circle is up to level 2, and move the glyph to the maroon circle, it will be 9 and 10 walking spaces away from each SZ, which means both sides have roughly equal access to is, and double spacers will still be able to claim it.
