This is a nice nerf. However, there are easier fixes to start with, such as releasing tiers with only 1 end boss rather than 2 (Tindral is arguably as hard as Fyrak) on top of said tier being closer to an useless season nobody asked for (fated).
Back in Antorus, we had 2 end bosses that were hard, but I wasn’t stressed back then knowing I had 1 year. Now, many mid range to casual CE guilds (WR 600 and beyond) are just stressed about getting 1 clear, let alone reclears to give everyone their deserved ce.
