Assault's 62 kph is enough to keep up, or not fall behind too much if you want precise terms, with heavies' 64 IF you look at the map and see where it goes.
This hasn't come up so far in this thread, but do people generally realize the tonnage tradeoff most assaults have to make in order to have comparable speed to the slowest heavies?
A Warhawk or a Mad IIC with a 340 XL to match the Night Gyr's base speed has a total payload of around 43.5 tons. A Night Gyr has a payload of 40 tons. Running an XL360 on a 90 ton machine to reach 64 kph is a 45 ton payload. You'll note serious diminishing returns even with the wonder machine that is the Clan XL and the benefits of Clan Endo. Both are required to achieve these numbers. The disparity becomes much greater on the IS side when you're no longer dealing with XL tonnage savings and Endo becomes a more troublesome proposition with 3-slot DHS.
A Battlemaster with a 340 Light and Endo Steel has a payload of 36.5 tons.
Does everyone understand the pattern here?
Those huge engines consume all the benefits of using a heavier chassis. You gain more armour in exchange for larger hit boxes and usually a drop in maneuverability. If your basement speed is the same as that for a slow heavy mech, you're quite simply better off choosing a heavy chassis with the right assortment of hardpoints and profile. If you want to go faster than 64 kph, then an assault chassis will suffer a net negative over a heavy every time due to the non-linear scaling of engine weight.
Building your assault mech to keep up with a lighter, faster team is a losing proposition. Clan assaults currently skirt the edges of it to maintain parity with their heavies due to the benefits of Clan XL and Endo. IS assault mechs are in a bad place, but it will be routinely glossed over because Mad IICs and Deathstrikes are still common on the field.
