Eve Online: Tuxford explains unannounced ship speed changes

Tuxford has made a post on the Eve-O forums going into further detail about the very noticeable changes made during todays downtime:

Ok heres the deal, we've talked about reducing speed and stuff like that. Everybody seemed to be in the agreement that some kind of a stacking penalty was the way to go. Here's the problem with that, there are two many things that are being modified. We have the speed obviously, we have the mass which indirectly increases speed of mwd and and we have the propellant injection vent which increases the boost of the mwd.

Up until rigs there were only two ways modules affected speed. So when the propellant injection vent came along it gave an option of 15% boost which wasn't really stacking nerfed and more importantly couldn't be stacking nerfed with the other modules rigs. So knowing we ****** up it would be great idea to go back through time and take the rig out but thats hardly possible. So we did the next best thing we could. We morphed it into another rig, mainly the auxiliary thrusters one.

Why didn't you tell us
I was going to honest. We was debating whether we wanted any sort of market speculation going (anyone remember tractor beams incident?) but we figured there would be no way to exploit that knowledge to your advantage. So I was gonna post to day but because of a little miscommunication between me and the operation guy that actually did it he did it today and not in the downtime before the next patch.

Zomg my ship goes a lot slower
That was rather the point. What happens now, well after next patch that is overdrives will be stacking nerfed together with mwd and auxiliary thrusters, nanofibers will be stacking nerfed with each other and polycarbon engine housing so velocity doesn't come down to who's got the most low slots.

Will I be compensated for the rig?
I'd would like no one to feel screwed over but in reality its just unavoidable and we can't compensate everyone in a way they think they should be.

In the end I'd just like to apologize for not announcing it sooner and that we had to go this way to fix the problem.

P.S. Because of our little misunderstanding Tech 2 versions are still dropping so we're running that script again before downtime on patch day and after that they won't drop any more.

I kinda figured this one was on the way after Tuxford talked to me for a bit last week about EVE and one of his questions was "Do you think ships go too fast?"
