Isn't hard by much, if the sepaphs and Stewards were reduced in number by 33-50% it would be fairly easy to do. (May also need to remove a few war production building aswell)
Worth playing. As usual on 1st day of event I take damage . Then I watch some online videos and it becomes easier (although still tough) just managed to finish it the now. I will start 2nd run later today. I would say it is a bit too tough though.
A lot of people will not be strong enough to finish event. At least give them a chance to get faction 3 done and get a few new units.
For me the difficulty is fine but the payout is Low to get trophy-tech-seraph-training-token
And each base take about 15-20 mins to open with Low repair
Either increase xp payout or reduce the xp price by 40%
