1. For me, my opinion is losing 3k to 4k power is not good since i'm addicted on increasing my power this days .. I hate seeing my power go down and it happens everytime when the Summon Chakra Consumption goes down .. I already have a complete 1 set of Lv.8 runes and 2 sets of Lv.7 runes as of now .. whenever i gets a rune, i sold it for points and i took Kirin first as my Fire-allControl team needs it (MaskedMan team) but then, now i'm piecing KoH slowly, currently sitting at 15/80 .. i only use points i get from events and from selling spare runes ..

2. KoH is good for every main i guess, as long as your team is high-hit combo type then KoH is the best .. I actually need KoH now that i got Angel complete but i still don't have Kisame or Kakuzu that can give high-hit combo for my team so i'm taking my time waiting for me to pull my first SR in summon treasure while collecting KoH frags slowly ..

3. It will turn to Summon Points.
