Okay I have a few ideas, feel free to +/- them:
1. Implement a x2 one saturday per month, this is because, in all honesty our x2's are really random, having it scheduled for example, the second saturday of every month gives you time to plan ahead and farm cards and whatnot, and I picked saturday since it's already a pve day (morai, ares, etc) at least the past months there hasnt been a single pk on saturdays other than a random tw or some pk at morai. Also, if there's a previously scheduled x2 due to a festivity (for example christmas, halloween, epw anniversary, etc), the x2 saturday of that month will be suspended.
2. Boost the rewards of Ares to 100 ec, 2 ET, 20~30 st, 1 cog/wwi and 1 universe chest but remove the morai event instead. Basically merge both events, this is kind of to go hand-to-hand with the idea above, have more time and such, and nerfing the morai alts spam since they have to be 150 now instead of 145+.
3. The last idea is implementing more weekly logging events like we had during the EPW anniversary of 2014, I dont recall much of it but you got random freebies during a week, the community can vote on which days this would be convenient but we can agree on Halloween, EPW's anniversary, Christmas and maybe New Year having this by default.
EDIT: The daily logging rewards would apply only to lvl150 chars and require you to stay logged on for 15-20mins.
Feedback would be appreciated.
