Well you aren't really counting coins and Hidan frags. Honestly this event is good, free 350k/140 coupons/70 Hidan frags.

Plus you actually have a choice, you can aim for 1-3k range, it's pretty each to control the lantern. You can go for 140k/35 purif/14 Hidan or 70k/21 med refine/14 Hidan if you think those are better.

I am getting Hidan on purpose, saves me 14k Arena coins, med refines are good option as well but i need adv ones more at the moment, that would be my 2nd choice.

You don't have to launch your lantern at start and use all 20/20 supports. You can launch it near the end to make sure you get less then 1k from time, then only do 10~ supports to get 1-2k or 20~ suports to get 2-3k, don't request support.

Nah it's easier then it sounds, also i know med refines are good but i can get them at alright rate, on other hand i only have like 35k arena coins and i am not really spending them on anything. Saving 14k is nice, that's 35 days worth considering you can only get 400 a day, and i want to have all ninjas i can even if just for collections sake.

This event is already one of better free events we had honestly, as good as Lucky Bag or Puzzle, really out of all events people complain about the good one.
