My 2 cents reviewing this week's events.
Lucky board: While i support those asking for improvement inside the grid (advanced cloths/threads instead of medium ones, maybe switching jiraya for another Event ninja like Samahada Bee or Hanzo), this is still the most efficient way to increase both power and lineups. Rewards are good, even if i would have liked Tendo in the place of Sasori, but this is just cause i've never seen him in an event before. I would really like to bring him to 4 stars.
8/10 Great with some range of improvements.
Goldfish: While being a free events, i strongly believe that fishes should give you around 50% more points. At the moment, i see this event as a waste of time. I dunno if i should go for Gai (for refine fragments) or whatever else. This event could be improved giving us a way to buy GNW ninjas. Sign in ninjas for around 50 points/frags (with the actual point system) and event only for 75 points/frags. This way F2P players could improve what are essentially free ninjas or just unlock them if someone didn't manage to login for some days.
5/10 Could use some major tweaks.
Gift pack: can't speak as i only saw the first one. They are good for low levels who want to unlock tools or magatamas earlier with ingots.
n/a Can't vote without seeing all rewards.
Summon rebates: Not much to say. Gives rewards for using summ scrolls. After an event who will give you tons. Also, wednesday we will be able to get also those 100 monthly points while still in time for this event.
7/10 based on last rebate rewards. Extra points if you could remove 7 days scrolls for normal ones.
BA rebate: Good event. Nothing more to say. The only improvement i could think of is giving the rebate to those who upgraded the armor out of event, maybe reduced to 50% of the amount. I remember that spending a bit on BA to unlock the first 3-4 levels when i unlocked it before even knowing that this event existed, suddenly knowing that i have lost the possibility to actually get things wasn't that good. Maybe in time i would look for tobirama, but as those with lvl 9 already couldn't redeem this ipotetical new ninjas...
8/10 Great and solid.
