Any mouse, not equipped with the "single action, double click" button, placed beside the left button (number 1)= (to be easily accessed with a forefinger) is a fail, as far the gaming goes... That's why I'll stick with a A Tech X7 until it gets shattered...

Meanwhile pro's use the most simplistic mice with the basic buttons... Sensor is a 3361, modded 3360.

There is no such thing like 'basic' buttons. The first mouse ever produced had ONLY ONE (1) button. Way back in 1990-es, mice used to have only two buttons ("left click" and "right" click"). Then the "wheel" was introduced. After that, the wheel became a third button too, and for a long time it was considered a "regular" setup. And there is most certainly no "pros" and "amateurs" whom would have been possible to distinguish by their use of a specific mouse-configuration - whether one is a "pro" or an "amateur" depends on many other elements, such as what they do, where & how & why they do it etc. In regards with GAMING, this is also the case: either you like it ("I don't like reggae, I love it-a!") and play (games) or you don't (like them/play them), so you will do yourself a great favor by not flattering yourself being a "pro" because you're using a 1996 model, ball-roller based Genius mouse...

Proper gaming mouse, like HOTAS Joystick, allows you to keep left hand on movement keys (W,A,S,D,SHIFT,SPACE) at all times, while performing most basic FPS functions: M1 – Fire M2 – Aim Down Sight (ADS) G4 – NUM 4 – Side weapon G5 – NUM 5 – Prone - Fall to the ground G6 – NUM 6 – Main Weapon G7 – NUM 7 – Crouch, Cover G8 – NUM 8 – Heavy Weapon, Revive G9 – NUM 9 – Command Interface, Spot Target G10 – NUM 0 – Melee, Knife, Hand G11 – NUM 1 - Change Sensitivity G12 – NUM 2 – Drop gadget G13 – NUM 3 – Throw grenade I have Logitech G700 and still not enough buttons when playing Battlefield and trying to use all tools available. Proper gaming mouse must have 14 buttons and probably one extra axis to make sure that player keeps his Hands on Keyboard-And-Mouse (HOKAM) buttons at all times.

Not really. CSGO, Starcraft, Quake, ... Plenty of pro's making loads of money and the majority of them actually use mice with very basic shapes that just have a good, reliable sensor: http://on-winning.com/cs-go-config-setup-settings-monitor-mice-sensitivity-pros/ Actually, most decent to really great players actually consider a "sniper" button cumbersome and annoying. The Sensor in these new Roccat mice is significantly better then the previous generation.

And you own new roccat mouse so you know that sensor is more reliable or better than older ones?!

It's based on the 3360 and with previous sensors Roccat their implementations were always quite good (3090 on the Savu and 3310 on the KPM). If their track record remains the same, it should be better. The 3360 is simply on all fronts a better sensor then the 3090 or 3310. It's the public variant of the 3366 that's used in the newer Logitech mice (first appeared in the G502, but now also in the G900, G Pro and G403).
