A few years ago the Cromwell was an iconic unit for the UKF. It allowed a fast mobile gamestyle which suited the faction description of two styles of army in one.
It was never meant to be an infantry support tank, that was the Valentine and Churchill, doctrinally it was a cruiser for fast flanks and in game specifically for finishing off damaged vehicles. The Comet fulfills the generalist role and the Firefly the tank destroyer role.
The rebalancing at the time completely wrecked it, turning it more into a very inferior Panzer IV which ideally had to halt and was more AI focussed. In the midgame the UKF doctrinally relies upon IS, pit and the Centaur for AI work.
It is concerning to see therefore that rather than merely reverting the unpopular and unwarranted nerfs which were largely uncalled for by the community, most complaints seemed to centre around how early it appeared rather than it's abilities, that it's role is increasingly being sidelined towards AI work with a munitions ability to replace the highly skilled usage it was once famous for.
On the protection / mobility / firepower triangle it should doctrinally prioritise mobility, hence speed and manouvreability, and accuracy on the move towards targetting Axis vehicles.
Given the low number of useable UKF vehicles compared to other factions an AI focussed medium tank would be welcome, though historically that would merely be a reskinned Sherman or the Valentine. The UC and AEC are unsuitable for late game in any game mode.
The Cromwell should be a highly specialised machine that rewards skill, as it once did, and fulfils it's role rather than a homogensied generalist tank of inferior performance to it's contemporaries.
