I have spend most of my recent time in WT spading my CR2 and Black Night and I would without hesitation pick the Challenger 2 reload system over the T-72s. The 4 round ready rack might be empty quickly, but for burst or close range fighting the 5.3 second reload is a life saver.
(Overall I have been really pleasantly suprised with the Chally 2s/3 TD, especially after having read all the doom talk from British mains on reddit and this forum about it.)
I dispise using them nowadays at those Brs, when I can really just take out an abrams, leo, leclerc or my favourite the Vt4A1 lol.
T90M is quite good fun as well.
CR2 isn’t like it’a useless at all, but you definitely have to try to play it oppose to the aformentioned tanks in which you can afford to make more mistakes.
CR2 has the 2nd worst top tier round, massive issues with it’s armour, mobility is horrific as it drops way too much speed turning. Ready rack is wrong as well.
That does0t mean it’s not gonna mess stuff up if used right though.
M1 reaches position 1 in around 43s
T-72B3E reaches position 1 in around 54s
M1 reaches position 2 in around 50s
T-72B3E reaches position 2 in around 63s
M1 will literally reach position 2 before T-72B3E can even get to 1, and this one of the more favorable maps for B3E as it does not include offroad or much turning.
So no, its not enough to get to where you need to go.
