With the new MCH changes, the class was pushed in what some (myself included) feel is a better direction to move in. It placed the focus more on getting as much mileage as possible out of overheating, which is a good direction for a burst phase-heavy ranged DPS.
The problem, however, for MCH and any other class that has a lot of oGCD abilities, is that oGCD abilities get a bit dodgy when used in rapid succession, but "rapid succession" is exactly HOW we need to use said abilities in order to get the most out of these classes (such as NIN with mudras).
Here's a slow motion clip of two MCH oGCD abilities failing to activate when pressed:

Rapid Fire is pressed but fails to execute at 15 sec, Gauss Round at 30 sec.
The key problem here is that these abilities appeared to be functional and ready to use before being pressed. In the video, both abilities have their corresponding hotbar buttons light up when they're pressed, but they simply do not activate.
Unlike with regular GCD abilities that have spinners over them and will elicit both an error message AND sound effect informing you that the abilities didn't activate, there is no such feedback given to the player when an oGCD they pressed failed to activate.
I'm guessing this problem could very well be ping-related, not that my ping is high, but I'm on the east coast so I'm a bit further away from the servers than many players.
Either way, this is a serious hindrance to being the best player I can be. The end result is that I need to mash every oGCD ability 4-5 times to ensure it activates, which means I'm not pressing my regular GCD abilities the moment they're off CD. It's also hell for trying to get the most out of Wildfire, in which I need every oGCD ability to happen when pressed to maximize my damage.
My request to the devs is this...
If for whatever reason an oGCD ability isn't going to activate when pressed, we need a visual indicator to inform us of this (aka an oGCD spinner that informs us when it's clear to press the next oGCD). It doesn't matter whether this is due to latency, "animation lock", or whatever, players NEED to know when pressing a button isn't going to activate the corresponding ability.
Or alternatively, give us a more generous buffer for stringing several oGCD abilities together in a row, maybe placing the emphasis client side so we don't have to press each oGCD multiple times before it activates.
In the end, the whole reason we call these "off global cooldown abilities" is because of we can supposedly activate them free of any timing restrictions. If timing restrictions do indeed exist, we either need some means of removing these restrictions or an indicator of WHEN we're restricted from activating them.
It'd also be nice to hear from other players regarding their location and whether or not they suffer from these issues. I'm ASSUMING this is ping-related, but there could be players living a few miles from the server colo who have these issues so more data is always useful.
