So, Season 2 finally came out, and the response to it hasn't been great.
A lot of old problems have reared their heads again, like some new terrible challenges (which are still the only way to progress, by the way). But one thing that has really caught people off guard, are some of the "fixes" that 343 have put into place.
In campaign, for instance, the developers unintentionally left over a weapon that could be picked up - The Tank Gun - that gave the player an invisible gun that shot tank shells. Intentional or not, players really embraced it, and it was a lot of fun. Its not without precedent either, because Halo 2 had a similar super-gun easter egg.
Removed.
There was also another exploit that a lot of speedrunners used, where you could stand on a fusion coil (an explosive box, that you can pick up an throw), then use your grappling hook on it, which would then propel you far into the air. Again, a lot of fun.
Removed.
A glitch where you could unintentionally fly a Pelican dropship?
Removed.
And these are all from the singleplayer portion of the game, too! Where the developers explicitly stated that they would not remove exploits like these, unless they were literally gamebreaking (crashes, etc).
Who called the fun police?
One other controversial change in the multiplayer side of the game, was the removal of a lot of skilljumps, which a lot of the pro players used. Skilljumps would exploit the geometry of a map for a shortcut. These have been included (intentionally or not) in many other past Halo games, and these have always been embraced as part of the pro scene, which 343 has been eager to foster.
This is the first time that I am aware of, where any of these have been purposely removed. The pros aren't happy.
Its just quite funny, because 343 does these blog posts, where they collect feedback from players about what they want fixing/changing, and then 343 speaks about each one, talking about if they are going to address it, when the change can be expected, etc.
None of the above changes were brought up once. Because why would they? Meanwhile, loads of changes that have been requested, are either not going to be touched, or are still somewhere in the pipeline.
343 really can't seem to do anything right.
