The initial class burp was all focused on support chrono and mirage, and then you have this here sneaky little change:
"• Signet of the Ether: This skill's recharge time now begins at the same time as phantasm skills are recharged."
Why? Why completely kill dps chrono without any compensatory buff? Even a nerf to Danger Time without at least reworking it so that it becomes a lot more realistic to take in pve scenarios, since slow uptime is quite limited.
The dps numbers were perfectly in-line with the rest of the meta, the rotation was fun and engaging, and we are not going to get a new expansion for quite a while, so it's not like mesmer was going to get a power spec any time soon. So of course the most logical thing to do was kill power chrono. To say that I'm extremely disappointed is putting it lightly.
