You don't really need a Dancer for links, they're just another link class. Lands use Links in a specific, powerful build.
For a Land Link build, you use Land/Runemaster, and the skills Vanguard, Improved Link, and the level 40 one that increases damage. Links are basically subsequent added elemental damage attacks added to the base attack. You get your Land to attack first using the skill Vanguard, and every person who attacks after gets additional elemental damage. When you're exploting a weakness, this elemental damage can be very impressive, but even when you're not it still adds quite a bit. For example, it effectively doubles or triples the attack power of a dual-wielding Nightseeker.
You can also do Bind chain parties with Arcanists and Snipers, but it works a bit differently and focuses on the Sniper's Critical abilities and add/remove Binds.
