I find it funny how you say people are lazy if they prefer to play with a controller and they do not perform as well. For one I am a console gamer and to me a controller 100% more natural to me and I am more effective with a controller than with a keyboard. Generally I do use both depending on the situation but I mostly use controller and in no way am I gimped to my counterparts who use a keyboard mainly. I have all the functions at the same speed that I possibly need on the controller and if for some reason I don't have the button I need to get to whatever I reach down and press the button on my keyboard.
Thanks to fully customizable controller layouts that have all possible buttons needed to play the game at maximum effectiveness for someone who is used to using a controller over a keyboard and being able to make macros to do any action with the press of a single button makes your whole argument useless. I never get a single complaint about not doing something quick enough or people ever asking me if I use a controller because it seems like my skills are being diminished. Because you don't use a controller well doesn't mean others who are used to using them aren't just as effective as you with a keyboard and mouse. I will admit to there being certain limitations and the fact you may be able to go through your menus quicker and what not but to be I am never in my menus in battle and I am at my optimal speed using a controller. (On a side note I am used to playing on both Keyboard & mouse and/or using a controller, When I played WoW I couldn't use a controller but when I played FFXI I used nothing but controller/keyboard combo)
As for controller type I have a PS2 to USB converter and I use a PS2 controller. Controller of my choice over Xbox pad because the DPad is a million times better and doesn't break or wear down nearly as easy.
