Just a fun, random fact for your consideration:

The average system (50 AU wide) contains something in the region of 113,097,335,529,232,556,584,655 possible 250/250/250 grids. This would be enough to give every active subscriber in EVE Online somewhere around 226,194,671,058,465,113 grids of space (or 3,534,291,735,288,517,393,270,468.75 km-¦) to themselves.

Across EVE's 7930 systems, there is something very, very roughly in the region of 896,861,870,746,814,173,716,314,150 grids. This would be enough to give every active subscriber 1,793,723,741,493,628,347,433 grids (or 28,026,933,460,837,942,928,640,625,000 km-¦). Each player could keep almost exactly 25,873,961,153,274,012 copies of the Earth in such a space.

For every AU you warp, you cross precisely 600,000 grids. An interceptor warping at 12 AU/s crosses 7,200,000 grids a second. It would take an interceptor 3,949,903,244,382 (three trillion, nine hundred and forty nine billion, nine hundred and three million, two thousand and forty four thousand, three hundred and eighty two) years to cross every grid in EVE even if they were all laid out in a straight, unbroken line.

... but you'll still complete it before the whining about the warp changes stops.

A perfectly reasonable fix was already suggested. Simply keep warp speed deceleration the way it is pre-Rubicon, giving pilots the chance to see a ship landing on their grid. The initial acceleration being fast is fine since the intent of that change is to see where an enemy is headed and get there before them. Increased acceleration from zero coupled with the higher warp speed of interceptors and dictors achieves this goal easily, but having such ridiculous deceleration coming out of warp is overkill and clearly broken.

There's no need to mess around with server ticks (on hardware that is already routinely stretched to the limit on its 1000ms ticks as it is) or increase dscan range (making dscan unbalanced). Just keep deceleration as it is now.

Alternatively, if you truly want a band aid solution and keep deceleration stupidly fast, give dictors a cooldown period where they are incapable of dropping a bubble for some period of time after dropping out of warp similar to a ship having a locking penalty after coming out of a cloak.

BTW, this also means that ceptors also instaappear on grid, right?

Here's the key thing to remember. Virtually the entire impact of these changes is ties to deceleration. Warp top speed isn't actually changing much with the changes (and is actually going down for the fast ships), the problem we're fixing with this whole feature is how acceleration and deceleration used to be the same for all ships.

The part of this change you don't like is also virtually the only part that has any impact

Good changes. However I'm kinda annoyed that the warp speed rigs will affect CPU grid. that will eliminate/change their use from a lot of doctrines that would have used them otherwise. (for example the awesome 4 rep scimi one of our guys cooked up that warped as fast as assault frigs for shield AF doctrines)

Other than that, +1
