The intended rewards for doing Casual, is just shipgirls. Equipments may or may not be part of the reward.

Casual is aimed for people who are lacking of time and lacking of good fleets. For beginners, the rewards are very useful than the equipment itself, moreover, for ship drops, you have another chance to get them in the next event, earliest.

So, when you are talking about restriction:

If you plan to get equipment rewards, you must start at least on Easy.

In term of difficulties, If you want to do hard, you must do in this order: Casual - > Easy - > Medium - > Hard

If your latest map you are done on Casual, you can only do hard in the third map (first - easy, second - medium/normal, then third - hard)

For example: MO4 - Casual, then EO1 - Easy, EO2 - Medium, EO3 - Hard.

No jumping from Casual to Hard.

TL: DR Yes, doing Casual earlier restrict you unable to do Hard until you reach EO3. And unfortunately, you cant change difficulties of previous maps
