if you continue playing this line, make sure you have a good crew.
Without a good crew this line is garbage.
Camo is 100% needed and sixt sense.
then brother in arms and then all the view range perks.
That said, i massively hated the setter, the tier 8 is better since you get some alpha and pen.
You play mostly as a bush camper that spots for his team, only firing when no one can see you.
The tier 10 is a good bush camper, but feels like a massive down grade over the tier 9, because of the gun elevation and depression, you can't aim up, at all.
Never try to circle anything.
Gun handling is crap and the entire line can't turn.
Always equip bino's, if you don't, play another line, this is a passive spotter line and it needs all the view range it can get.
In a 1 vs 1, you will always die, unless you can hug them and you are lower than their gun. But be warned, british light tanks weigh absolutely nothing so you have to keep them tracked, if you don't want to get pushed.
You can be pretty helpful in city's, just support the medium tanks. Never go alone. And if your medium companion is on the brink of dying, find a new meat shield.
And most important of all, ignore your chat and all the pinging.
