They nerfed Kill-stealing!

[Lanei]

* A hero will now get defeat task credit for any villain defeat where his team did at least 25% of the damage to the villain and they are within 200 ft of the villain when the villain is defeated. This is to minimize the potential impact that "kill stealing" may have on the completion of defeat tasks.

Apparently this patch was rolled-back pending investigation of why it broke some unrelated functionality.  Devs have already posted to the effect that:
* Yes we know we need a public test server
* The hardware that was going to be a public test server became a live server instead
* The new hardware that will be the test server will hopefully be set up this week, unless E3 pulls people away from doing that
* If the test server gets put up, the patch may go on that for testing until after E3

Wow, they're working on patches.   For a moment I was wondering if they were too busy giving themselves a pat on the back to continue work on CoH.

Technically this wouldn't be a kill stealing nerf so much as crediting all involved players with a mission kill count so long as they're still within close proximity and have done at least 25% damage.

No - they were too busy nerfing Hasten...

[geldonyetich]

Bah!  They've already nerfed Hasten to 33% in the last pre-release patch. Granted, if any power is nerf-worthy, it'd be Hasten.  Nonetheless, the Nanites has hasten.  I want my power pick back if they pull that shiznit again.

Right, thus greatly reducing the incidences of someone actually depriving you of anything at all when they ks one of your mobs.  This is a good thing, in mine sight.  Calling it a nerf of KSing was an attempt at humor.

In related news everyone appears to be rolling up a character that can charm.

I'm glad to see them say that the machine they were going to use for a test server had to become a live server instead. Meaning their inital projections were surpassed by at least one server's population.

And because the more populated servers don't need anymore people on them.
