The thing that really confuses me is why did Valve pick now to nerf the sticky launcher? The answer seems to pretty much be the parachute, but the game is 7 years old and the game was well understood. From about just before i46 until about just after i49, class balance never really changed much, new unlocks/changes to existing weapons didn't really have a massive impact to how the game was played and you could see the impact it had, strategies and gamesense were at a better point than ever, when the game has remained roughly constant for that long, you have to concentrate on the smaller deficiencies in your play to get the edge. And now that's gone in an instant. Someone commented earlier about how no one would be complaining if this had happened 6 months after the initial release of the game and that's right, it would have been OK then, people would have adapted and 7 years worth of strategies and gamesense would have been built on that. Now it's back to square one with everyone learning.
What I would be interested to see is the reaction of people who currently support the update if it were to be reverted.
