I think it should come down to where it is a flat standard across the board, No Assault Bot should out run a Light, No Mech out run an Assault, and no Heavy Mech out run a Mech. So if that means adjusting speeds within the game, so be it.
Lights are just that, lightweight, light guns, the scouts, by rights. They are fast, at least in to 110 KPH if not faster. Fitted with Sensor boosts, they should be able to out range any other bot / mech electronically, (unless damped / area jammers....New modules?) so they see trouble before actually running into it at optimun range of Mech with demobs and get 1 shotted.
The Assault Bots are the Anti Scouting Bot (area Jammers to reduce radar range within a specific radius) / Heavy Scout and General Purpose use . They should be be in the range of 90KPH.
The Mechs at 70 KPH are the base EWAR / Battlefield Logistic platforms and or fire support.
The Heavies in the 50 KPH and basicly a walking (EMPHASISE WALKING) Turret of firepower and armour or Heavy EWAR / Battle Field Logisitics.
These should be the standard speeds with 0 EP bonus's or Lighweight frames applied. When you have Mechs out running Light Bots, you know the game is not balanced quite right. Ok, you strip ALL the armour out of a Heavy, and have the lightest of modules fitted and have Navigation at 10, then at most, that mech should be doing 76 KPH.
If you want speed, you have to sacrifice something, that being Armour and modules.
Maybe bringing into the game engine upgrade modules (Low Slots). An example might be better plasma injectors for an over all increase of 3-7% speed increase based on the Tech level.
What this is intended to do is make the Squad Leaders / Patrol Leaders think about their squad composition and bring a little bit of complexity to PvP ops make up rather than everyone load up for bear and going pew pew (which is fun but tends to get a little tedious after a while) It is also a means to ending the blob per se, where you have a gang of gun ships, torn apart because their composition was not thought out properly, got sensor damped and ECM, and picked off by a lesser number of opposing gun ships but who had the right logistics and support in place.
Just a few ideas anyway.
