*Updated with suggestion and a more concise complaint.
Please allow us to buy the page 1-5 orbs with merits, or give us a blanket key item obtainable via merits that we can also use to do the fights.
There is a huge time/cost disparity between obtaining pages 1-5 and 6-10. You clearly place pages 6-10 on a considerably higher tier, it is evident from the cost disparity of the pages via login points, sparks, and the difficulty of the fights, yet they are so much easier to get. I can farm 45 merits in about 20 minutes, and complete an upgrade piece + extras within the 8 runs it requires. Usually totaling less than 2 hours. On the other hand, it takes me about 200 farmed merits to aquire enough seals to do a 1-5 BCNM. Sparks farming is also extremely time consuming, assuming gain xp limited is not up, it can take upwards of 5-8 hours to complete one item.
I also dislike that I am basically forced to use/convert all of my seals for these page 1-5 fights instead of doing other content with them.
