enemies in hard mode currently have a substantial recharge reduction.

• sample video of two mobs casting more frequently than they should.
• a recharge reduction is not historically part of the list of buffs that enemies receive in hard mode.
• it looks like all enemies have between 25%-40% recharge reduction on all skills.
• this effect is not caused by other skills such as weapon of quickening or quickening zephyr.
• anecdotally, this effect may have been introduced in or around the mesmer balance nuke patch.

i don't think this was discussed in any patch notes? that's quite a big change to slip in.

edit: JustARandomBoringGuy in the comments has supplied evidence of this being in game for a long time.
