Monk Gathering Storm supports

I really appreciate the game having tooltips on everything now, but one thing I still have to resort to resources outside of the game is - how do you guys determine which supports work with a skill, and which are completely useless?

I'm playing Gathering Storm as a 1 button build, and Innervate clearly works, because I can see the damage increase in the tooltip.

I can't see Momentum, Potential and Window of Opportunity doing anything at all, the damage and crit chance doesn't change.

The skill tree and support gem upgrades dont seem to show for conditional effects. Momentum only applies after a certain distance and Window only when you hit the perfect timing. For example conditional evasion buffs on the tree(like full health or after shield starts recharging) dont show because they are conditional.

I guess for now you have to calculate for yourself. From personal experience I can tell you window of opportunity adds a nice bit of damage and momentum adds even more damage where you land. Ambush isnt bad on gathering storm either. If you have alot of shock synergy then adding lighting weakness on shock from gathering storm lets you clear out whatever survives the initial charge.

Thanks for confirming some of those work!

Yeah what I've meant is I test it like this - open a skill tab in a pack of mobs and do a thing, sometimes you can see transient effects from supports changing the numbers immediately, but in this case - it also switches the tab from Perfect Dash which makes seeing changes impossible.
