Easy my fucking ass.

Don't try this kids unless you have stupid gear. FUCK Ionar.
You don't need especially good gear to do it this way. The trick is to

a) be spaced far enough aparty that the debuff he applies (which does damage to players near the player with the debufff) doesn't reach the next player and

b) to use a nature resistance totem

If your all teammembers can cast heals, use the heals on yourself while he's dispersed, if you have only one healer, you need to be in position to do AE heals (for instance PoH works really well for this encounter).
