Changing from 1.5-1.6 was changing mechanics, this is literally changing into a completely different game.
People thought these same things about CS:Source, and it wasn't more true then.
The sponsors need to pick back up 1.6, or CS:GO will change the CS community like never before.
It will be a sad day to me (as someone who has played since beta v1.0) if 1.6 goes down and CS:GO truly becomes the new game. It will be a CoD-esque feel and saying the name "counter-strike" will just not have the same meaning it used to.
The game is in a terrible state and it's currently run by a company with an awful track-record as of late in terms of producing a quality game.
There is little chance of CS:GO being a game that even contends with 1.6, so outside of players who still have some sort of aspirations that they'll "make it big" with CS:GO - or players who will be sponsored and paid to play it, the falloff would be noticeable and the new players coming in would be the nail in the coffin on the CS we used to know.
not the sponsors destroyed this game...the teams destroyed it...big teams buying players from not so big teams....there are no new talents... the last example is trace..Fnatic took Trace from eSrael and so the rest of 4 good players are "free agents"
