Now to me, that can be read as "We're having a spot of difficulty finding suitable vehicles."
So lets throw together a Scout tank tree to help the dev's.
Obvious place to start is the Vickers Light tank at tier II. It has similar guns to other tier two tanks, such as .50 cal and the 15mm.
Tier three is also easy, The Harry Hopkins Light tank. Designed as a bigger and beefier Tetrarch, and as the Tet is Tier II, it makes sense to make the Harry Hopkins Tier three.
Now comes a problem. Tier IV. The Problem is for the later years of the war the British tended to use Armoured cars for recce or the Stuart (which will be making an appearance in the Lend lease tree). Of course a Stuart Jalopy would be a very unique vehicle...
The other candidate is the Vickers A45 (no not the Centurion, the other A45). It was later re-built as the FV-301, however at this point it looks a bit too powerful for Tier five. 77mm gun and quite a bit of armour, leaves it squarely in the Tier 5 bracket.
Tier five and Six abound with designs. The aforementioned A45/FV301, TV-15000 (Not a Scorpion!), the TV-10000 Rhino (with a dash of imagination and fudging) or the Prodigal light tank project (Although looking at weapons its almost defiantly in the Tier 6 bracket!).
I suppose chronologically (and from a weapons POV) the TV-10000 Rhino could be a Tier IV derp light, and not break the game.
