When mechanical boards were becoming more prominent in the gaming scene, a complaint of blues (and thus greens) persisted around the issue of double-tapping. While on a personal level, I can understand the point due to the way the mechanism works, it doesn't hold up for anyone with a familiarity of their switch. It's a relatively small adjustment and presents no problems for games.
That really depends of the game. Some games are "input sharp" and Clicky switches would be an handicap. In SSF4, using blues would utter suck when it comes to fast input registry (Think the Shoryuken with the arrow keys, you have hit forward, let it go, hit down, then rehit forward). My friend tried with green and said combos wouldn't registered properly versus linear or tactile keyboards. That is less of an issue since those games are usually played using other hardware (X360/Xone/PS3/PS4 controller or arcade sticks).
Akuma has a DOWN DOWN DOWN (Three kicks) (or 2 2 2 Three kicks with numpad notation) Combo. That is impossible to register with clicky MX at a faster speed and as "sharp" than any other devices.
Guiles Ultra Combo, Flash Explosion, is (numpad notation) 1 3 1 7 + Three kick. That would be impossible with clicky arrow keys as you will need to release and reinput three times the down arrow.
Also with Counter-Strike GO, i'd say playing with clicky switches sucks. The game is a little less "input sharp" than SSF4 but sometimes you need to be really sharp with your input in order to achieve some long jumps or other fast movement air-related operations. I tried it with MX Green and it was plain bad, the worst in MX so far.
I have about 1500 hours recorded on CS:GO and tried on Topre, BS, MX Red, MX Green, MX Black and MX Brown and looking forward to Clears soon, but i'd say i am personally more comfortable with Browns and most of my friends play on Blacks. It would of course be playable on Clicky switches but i strongly believe it's a poor choice when it comes to optimisation.
I guess I never got the double tapping thing, Im not sure what you would be double tapping. Im also a primary FPS player though so I dont really need to do that, never played DOTA and Im not even close to fast in SC2. I have no issues gaming on blues, I got my Clears board and I just like that one better. as long and you don't want to hover on the keys and you do a full press and release every time your fine.
In Minecraft you double-tap W to run forwards.
Yes but the double-tap counter is slow to run in Minecraft. Some games needs some very fast double taps, the mandatory delay of the switch contruction is simply unacceptable.
