@OP If you have problem with same guy every ionization, why not have him stand outside the pool? It's not like enrage is problem on this fight anyway. I still wouldn't say it too unforgiving to give players 30 secs to move out of pool. Dispelling shouldn't be too hard either as long as they only dispel people who called it. Most annoying part about ionization is, when boss dies and people have the debuff on pool, it expires and kills everybody that's standing on the pool.
