**UPDATES TO ENLISTMENT GIFTING EVENT:**
To prevent exploitation, we will prevent new Accounts from being able to Gift enlistment crystals. We will also be taking action on those who are using 3rd Party Sellers, Bots and other farms to gift themselves mass amounts of Enlistment Crystals. Lastly, we will be adding an expiration timer to Enlistment Crystals. All unopened Enlistment Crystals will expire on Oct 18 @ 17:00 UTC. For more information, please see this post: https://forums.playcontestofchampions.com/en/discussion/346104/updates-to-enlistment-gifting-event

Dungeons : Are you gonna play ??

Comments
If they end up doing a dungeon day again (with the boosted rewards based on prestige), then I will go back in and grind all the milestones. That was literally the only day worth grinding dungeons IMO.
Probably best to start now if you plan to open any of the dungeon crystals... It will take you almost 27 days to collect enough for 1 5* crystal. I believe that they are worth it in the long run because you will have the opportunity to open a crystal with 10% chance at the specific champion you want. We rarely get those odds with the number of new champs being added so I would take that opportunity if I were you.
If you cannot communicate with the partner on voice or in another way there's no way to have a simple positive dungeon run.
That's -
(25,000,000/1,000,000)*0.5 hours = 12.5 hours of grind to get the champ.
For Dungeons, I'd say it will take the same person about 20 minutes (9 hard fights) in Room 7, over 3 months for 2 weeks (14 days) which comes to -
0.33 * 14 * 3 = 13.86 hours
I think the numbers are comparable, given the 13.86 hours will give you 1.6 times a 5* crystal. Effectively, you can get 3 crystals in ~28 hours. The problem is timeframe, those 3 crystals will take about 4 months.
I made a mistake here, the 5* crystal can be had in 2 months, so the time should be -
0.33 * 14 * 2 = 9.24 hours
Thats still a better reward than the arena grind.
This. I don't have time for arenas so this is going to be the next best thing for me. It's more fun as well. I look forward to building a team of friends that don't suck at it and doing it regularly in hopes of getting Blade because it does not appear that I will get him any other way. (I can't seem to pull anything but IP from any of the 5* crystals.)
It appears my 300k account with a dozen 5* will progress too quickly if I have access to 5* crystals from the rewards so I won't spent any time at all going after a 4*.
