Combo Action Button

[Bourne_Endeavor]

Bad design being common doesn't make it any less poor design. One should not need an MMO mouse for something designed for both M&KB and controller.

Except it isn't inherently bad design to have multiple buttons for combos. Some people may dislike it, however that isn't the same as it being flawed. You'll fine numerous controller and Keyboard player who have no issues whatsoever nor do they want anything changed. So, at best, it's a subjective argument.

Jeez, I guess that Naga with a 12 button remappable keypad under my thumb might have something to do with that oddity. Surely not.
Also, you are correct. I'm playing an MMO, not a piano.

Now riddle me this. After using Impulse Drive and enabling use of Disembowel, for what reason does Impulse Drive remain on my bars?
I will never consider using Impulse Drive twice in a row. That would be a straight dps loss, not to mention screw with upkeep of BOTD. There is literally zero purpose to Impulse Drive once I've cast it and moved up the chain. All it does is consume a hotkey and button space.

Potential solution for SAM: Instead of removing combo requirements, cause it to set the combo button to the final stage of each and apply the effects gained from using the entire combo in the chain.
Example, hit Meikyo Shisui. use Kasha(Gain Shifu buff) then use Gekko (Gaining Jinpu buff).
Might change the way its used, but that'd be fine, in my opinion. POint is that the skill can be modified/improved.

There is no purpose to skills used in a chain to remain on my bars with later steps active. That is bloat in its truest sense.
Mutually exclusive skills can easily be condensed down without affecting the number of keypresses.
If you like having 4 different binds for a single combo path with no branches (Like DRG), then feel free to keep the individual skills on your bars with separate keybinds. But I'd like an option to layer them into a single key.

1 button pressed multiple times as opposed to 4 buttons pressed once each.

Evidently, seeing I have a Logitech g600 with the same twelve remappable keybinds and have no such issues.

The reason is pure preference. Unfortunately, there is no scenario where SE will make it optional. Like I said, they aren't going to spend the resources to make it work for PvE only to subsequent prune and limit new abilities. They'll simply use it as their catch-all solution, thereby inevitably forcing people into it as new abilities are added. With that in mind, I prefer the current layout than having DRG reduced to essentially spamming 2221-1112, which is basically the equivalent of a Healer. They aren't going to add nearly enough oGCDs to compensate pressing less buttons. And if they did, well, it sort of defeats the purpose anyway since you're back to being a "pianist."
