For people who finished Atlantis time before it gets really painful to gather a substancial amount of coins.
I doubt most players are able to gather 300+ Atlantis coins only from the Sea Dragons. (Yes, there are people that make it but im sure they are spending or lots of Loot ticket or lots of flasks 25+ or a combination of those)
This Atlantis was really drought to me. I dont use loot tickets but play manually or in automatic most of the time. I have used at least 15 flasks and only gathered 50 coins.
The offers are not too many, only 4 good offers and one more that brings you only 300 coins if im not wrong. And its not the best deal either.
So, with few offers to pick from, with low rates of sea dragon, they shows up yes but not as often id like and the amount of coins they drop not always is high(today i got two SD that dropped me only 2 coins).
I would like to say a couple of things that could improve the portal a little bit.
Lessen the gem cost at least to 300. We are paying 350 gems for a portal that is at least aged.
Increase a little bit the sea dragon apparition rate or/
Inceease the amount of Atlantis coins they drop.
Add Atlantis Coins drop to other sources in the game, they are so scarse that are like a legend.
Not F2P friendly as the others but could work for C2P players. Add more offers. Update them. Challange events have their offer schedule updated, as well as others events. However Atlantis only offers the day 1 pack. Its likely someone is trying to make Atlantis a Gem portal.
