It took us close to 30minutes to kill it in channel 1. I think It should take us a shorter time to kill the snowman.
Snowman hp is at a healthy place right now. Compared to when Snowman was previously released. The issue with Snowman currently isn’t the amount of HP Snowman has but the amount of idle/AFKers in Snowman. There is no incentive to participate and attack Snowman currently so most map maybe 50%-80% of the players are contributing while the rest are not.
The timer is 2 hour though. So to speak, you have 2 hours to kill it. And I agree with the posters above, the issue is not with the health, but the amount of afkers.
With that said, If you are not punishing the afk-ers with DCs the issue will still remain. It's not fun to kill a snowman in 30 minutes and get nothing good as reward. It was more fun when It only took 15minutes.
