The problem is the fact you are using the wrong map to level your CL. The correct map is 4-3, which is used for levelling ASW capable ships, e.g. CL's and DD's, as they lack the FP to secure MVP. 3-2 and 5-4 are instead mainly used for levelling heavier ship classes, like CA, CV and BB. I would personally recommend switching to 4-3, but it uses up a lot of buckets - so if you do decide to use it run expedition 2 constantly to prevent huge buckets losses.

Event maps get harder and harder the more you progress - naturally of course, because E5 would be harder than E1. But in terms of difficulty there are 3 - easy, medium and hard. What the wiki means by a change in difficulty is way difficulty is determined. In the past difficulty was determined by HQ Level, but now you can choose your own difficulty.

When you clear a map, the difficulty that you clear a map on is locked, and '''cannot be changed. If you haven't cleared the map beforehand, you can switch difficulties, meaning you can farm on easy (but do not fully deplete the boss gauge) '''and switch back to hard/medium to clear it.

There is no order of difficulties that the game forces you do to. However, there are main rules/exceptions:

1) You can only go up 1 difficulty at a time, e.g. E1 - Medium    E2 - Hard. However, you can drop down as many difficulties as you like, e.g. E5 Hard, E6 Easy
