If you aren't able to save for at least 4-5 months to fully benefit from fuku deals, then that is an issue since you aren't willing to save. Start to play more games where they have in-game currency that you can farm as you will notice you need to save so you can benefit from event and some f2ps need to learn that. It's getting annoying to have some f2ps who don't understand this...

I did not read anywhere where the person you replied said events are only good when you have money. He just pointed that those events are good to use your coupons/ingots on - well the only ones that f2p care about are fuku deals and missions. Historically, the weeks of missions and lucky board are historically the better weeks of the event cycle - unless you think the random rates of great plates is better than those weeks.

Back to my point, I don't know what kind of players are saying "boring week" or "saving week". If whales are saying that then that's their fault for buying stuff so fast and expecting fast releases. If f2ps are saying that, they shouldn't as need to time save. Now if you were triggered by his comment that people that are f2p and complain with "boring week" or "saving week" then he does have some point as logically what kind of week due these players expect to be not boring and they are willing to use their coupons and would they expect that week to continue every week? You should know that isn't going to happen. People need to learn to use their coupons smartly especially when I see people "test" to see if the rates of great plates are good or deal with RNG events.

You wait until you have up to 20k to spend to fully benefit from fuku deals...

Doing fuku deals every time it shows up gives you less adequate rewards and you'll be worse compared to someone who did wait. Now you might reply and say, how will I know what events will be with fuko deals, you don't. December was different because it was the holidays and the events during the holidays will encouraging spending therefore fuko deals appearing twice is not surprising due to this reason. So far, fuku deals has been with lucky stars.

Since you may not know this, great plates has been shown not a permanent event compared to an event like lucky board. It was an event back in 2017 but back then nobody cared for it then when it came back in 2018, people cared because of the ninjas. So it may or not come back for a few months just like other events have done so in the past (goldfish, the other fishing event)

Lucky stars is good if you plan on doing it for the redeemables, not for the RNG reward. The RNG rewards in lucky stars should be considered extra when you putting in coupons/ingots to get the ninja/item in the redeemable section. What you did was a rookie mistake and many fell for it. Hopefully you learned from your past lucky stars experience, and don't try hard for the RNG reward.
