In my Opinion the 2minute meta is not the Problem, but it's important that what you do within those 2 minutes is fun:
For Example 6.05 to 6.08 was the most Fun Samurai Gameplay, I've ever experienced since Kaiten also interacted with the 2 minute Buster. But without Kaiten, there is no flow state anymore, no Kenki and Weaponskill Interaction, just dull burst and no that isn't fun since Iaijutsu never changes and Ogi never changes, in fact no Weaponskill changes without Kaiten and that sucks!
Other Example would be Ninja, though I hate the Mug is now Trickattack rework (they should've switched Mug to boost personal damage and Trickattack unchanged) but even with that change they manage to make me able to play NIN without Macros, which is at least one Good Point and unlike Samurai, Ninja at least had no skill removed, just changed for the 2 minute meta.. but still playable and able to have fun.

The 2 Minute Meta works on some Jobs better than on other and they have to Bring Back Kaiten.
