I was just able to log in a few min ago
There is going to be some freebies associated with the down time. As I write this, the exact coupon codes and whatnot are still being worked out, but this is the thread to watch for them:
The Coupon Code for 3 Excellent Experience Elixirs and a Raider’s Reward Box is now available! COUPON CODE: REWARD2019 - 1/Account - available to redeem through April 30th, 2019
Supposedly the elixirs are BTA but the Raider’s Reward Box is BTC so be careful who you redeem it on. Have not tested myself yet
