Skill V ilevel

[Kabooa]

You could have iLvl over 9000, and if all you do is spam cure 2, your team is gonna have a bad time.

This depends entirely on context.

ilvl 9000 following current stat trends at -level 60- means you can just Stone2 any boss to death because you'll be sitting pretty with about 60,000 hit points, well over 25,000 heals, matching damage hits, having close to no GCD, and critting on almost every hit with a for-all-intents-and-purposes-infinite MP pool. This means if you're just spamming Cure 2, you can heal up your party faster than the skilled i200 healer using Medica 2, medica, or cure 3.
