Ok I see I need to answer myself
1. You don't need to wipe dalvik-cache because ROM wipes dalvik during the installing process.
2. In the first post it's written:

- If your current firmware version doesn't match ROM firmware version, wiping data inside AROMA is highly recommended!

So... if 22.2 and 22.4 are based on the same firmware version (XXEMR2) is it recommended to wipe? No.
The same rules applies to all my ROMs and I think it's quite logical. My ROMs have the following numbering system:
X.Y
X in this case is 22
Y in this case is 4
X.Y = 22.4
X changes only if ROM is based on new firmware.
Y means minor update based on the same firmware.
Whenever X is higher, data wipe inside AROMA installer is highly recommended, but it's never "A MUST" because I can't force anyone to wipe his data. Also, sometimes device works as it should without data wiping, so the best way is to try yourself. In case of issues, perform data wipe. Usually data wipe is really necessary when new firmware is based on newer Android version.
I hope I explained it well. But again - it's all in the first post.
