Lately, the mounted fight against the bosses have been really hard. In every of my last 5-6 ToC 5 HC runs, at least one have actually died, including me. They hurt like hell and are forcing us to switch mounts every 20 seconds more or less. It's insane! And on a side note, I'm getting spammed with "Immune" messages while fighting on the mounts, which is new as well.
Have anyone else experienced this?
