I've played this mission a few times - on DRG (failed several times) and BLM (cleared first time) - and it got a lot easier once I started first of all making sure that my gear was as good as it could be, and secondly making sure that I was following the proper kill order:
1. Magitek Claws - drop everything else to get these dead
2. THM; they cast Fire, Fire II
3. CNJ; they cast Cure and Stone
4. ARC; they use a frontal AoE
5. Other Magitek mobs
6. PGL
7. LNC
8. MRD
9. GLD
10. Eline. You can literally ignore her, in my experience.
...I think, anyway. That order always seemed to work for me.
Your aim is essentially to reduce the amount of damage-per-second that Ilberd sustains, by controlling the number of high-damage mobs on the field.
The biggest issue you're going to have is that something other jobs can do to help improve Ilberd's survivability (pull aggro of mobs with frontal cone AoE's so that, even if you aren't killing them, you can control if their AoE's hit Ilberd or not) is going to be difficult to impossible for you. For a class with low burst DPS and no aggro-raising abilities, it's better to focus on getting things sorted through the kill order.
