OK, Here goes. My first post. I just solo'd this thing (Easy Prey) as an Elvaan WHM32/RDM16 and survived, but with under 100 hp left and 21mp, and was aggro'd by a Too Weak Gob Digger when I tried to rest up after. YES, it can be done. The only problem I had was the speed of it's attacks, which I wasn't ready for. He did use Bad Breath, but I only got affected by Sleep, which he kindly removed when he struck me right afterwards.
Knowing the Malboro traits in previous versions of FF, I cast Barsilencera before the fight, but Stoneskin only lasted through 2 very quick hits. I tried to Slow and Paralyze him, but was constantly interrupted because of the speed of his attacks. My gear ranges from lv16 (scentless armbands) to lv31 (Maul), with Seer's Tunic for MP boost and Tiger Stole for Attack boost, and I cast Enthunder for additional damage on each hit. I am far from being fully armored and prepared for taking on this enemy, but with proper spell use, it can be solo'd, even by a whm. I only used one Cure III during the fight, and never used 2hr.
As for the people who can't understand why some people have problems and they don't, LOOK AT THE JOB. A Warrior or Paladin has a much higher attack and defense than a mage or a thief, although a thief SHOULD have high evasion. As such, WAR and PLD should have less problems than those with other jobs. My WHM has an attack of 113 and a def of 105.
