Looks decent. Its hard to calculate the value since if i calculate i wouldnt give any value to seals and summon scrolls, considering the value they give to power. Summon scrolls give some runes which can be considered as powering up.

Purely based on market price:

Seal scrolls : 125 *4 =600 coupons

Summons scrolls approx (60 coupons)= 60* 16=960 coupons...that would be a total of 1560 coupons almost equal to what you paid for, if you are buying them directly from shop

Considering the best prices of things.

30 medium refines = 30* 20=600 coupons( i am taking the price of medium refines based on the pack of 10 you can buy from shop this week)

6 charms = 6 * 80=480(80 coupons is the price from a deluxe charms pack. Charms are available at a even lower price from a sage key event which comes rarely and then there is the wheel at myoboku trial which is RNG).

20 myboku = 20* 7 =140 coupons( 7 in the sense 30% discount in treasure of the sage gives that price)

that would be a total of 1220 coupons if you had put in best case scenarios to get those power ups directly. Considering you got all those summoning and seals scrolls along with those powering up materials and we have charms and refines rebate this week, which would give you corresponding rewards, it looks fairly good till now.

Its a tough choice to be honest.

Pros:

1) You get advanced refines from sage world( a lot of them if you have good power gap over your competitors at that level). Initiative is one of the most valued attributes in the game despite giving less power, but it could help you to win the barrier and move first to have some advantage in PvP. Some people say it affects matsuri matching, but i have never seen that to work, its too wild a matching. Advanced refines are the sole reason to be freezing.

Cons

Depends on how heavily you are freezing. Some people go to the extent of giving up on nine tails, ninja exam, nine tails wanted missions( which most people forget to do anyway), and sweeping plot /elite instances, and avoiding daily practices. Depending on what all you miss you lose a whole lot of things.Missing nine tails is practically giving up minimum 25*4=100 coupons minimum , and if you finish top 3 its more. Not to forget the coins you get in nine tails, which would be needed for equipment strengthening or eight inner gates. Not that there are other power sources, but you will take a lot more time to reach you competitors eight gates value. If you are freezing at a early level, and chucking ninja exams it would be a lose of magatamas and powering up opportunities from ninja exams. You will be getting lesser coins from survival trial at lower levels. If you are less than level 70 then some important treasures like kage wont be open and you would be missing those free draws that would reduce your overall consumption of seal scrolls. The present daily practice has advanced refine and myoboku thing at the last frog, some freezers just click the last frog, some miss it too. If you are missing it then you are missing some more powering up materials.

What happens when you level freeze?(ideal case)

Initially, You will obviously have a power decrease and you would see your competitors in server and space time bracket slightly growing better than you. But later you use up your hard earned refines.. Get those level 9 or 10 refines( too ideal if you are f2p, but there are f2p's with level 10 refines albeit in the older servers) , and even though low in power beat up your opponent with barrier. But this has become less applicable with the rise of barrier breakers like roshi and lord kisame. And about losing out on magatamas and eight gates, you can eventually catch up because all power sources saturate, and you can get closer to them, but they still will have the slight edge, because they started early, but the gap could be narrowed.

Who does this style suit the best?

Its best for p2w players, because they could make up for the lost materials and power with ingots. But i have seen f2p players, successfully freezing and ending up with high intiatives. Honestly it depends on your bracket too. Say if one of the whales in your bracket decide to freeze, and you are with him then good luck. Then it becomes a matter of chance as he will be stopping in between to make sure people with streak lose it so his side wins finally(yes people do that). When your streaks gets broken then its about luck, depending on who is in your camp. ) More level freezers more hard it will be for you. This is actually a cycle. If everyone freezes then we are again back to step 1.

So there is no single answer. You would have to choose based on your bracket. But in my opinion, if you are freezing start at around 70, because you would be opening up a lot of power sources and treasures by 70. And be ready for the haters, and there is no less honor in freezing. You are not doing anything unethical. Its just a play style where you are prioritizing based on your needs. If you can handle it go for it. In general you are always better off with slight freezing in level to maintain a healthy power to level ratio(which is again dependent on your space time cluster and server),..

Lol..

I think i messed up the posts. It should have been a reply for another question..

I will try to make it more presentable next time.
