Monk balance act 2

I've cooked up a smart monk build, where the rotation goes as follows:

1. Put double orb of storms
2. Hand of chayula applies conductivity and voltaic mark
3. Tempest flurry to proc orb of storms
4. Syphoning strike to build power charges
5. Once you have 3 charges do Mantra of destruction into falling thunder

But I got hard-stuck on act 2 final boss (Jamanra). After +20 tries I've tried to use the bell and it's hearth-breaking that the meta strategy is to:

1. put the bell
2. hold tempest flurry

I've tried that and killed the boss first try...
I think that complex strategies should be rewarded. I suggest to nerf the bell, improve the cast time of syphoning strike and improve the falling thunder damage bonuses from charges. At the moment it requires a lot of skill to pull everything off and you're rewarded with a slow falling thunder animation and no damage to the boss...
