Thing is, focus sight increases its sight range, not its actual range. Thus if it reverses without focus sight it will still have the same range, just not its own spotter. But take into consideration that it will be reversing into friendly territory, thus it will 9/10 times still have vision of the attacking tank provided by either friendly infantry, or control points. I really dont know how big the effect will be, but I think the lol-reversing is still gonna be a problem.
My only hope is that the time it takes to de-activate the focus sight will give enough time for the flanking tank to get behind it.
Another good point brought up by nullist is that kv-8's are now gonna be almost un-faustable(like they were even faustable to begin with).
Good point, I hadn't thought of the friendly units still providing LOS. They will still have to deactivate it though, which at least puts more of a micro burden on it. But totally agreed that it will need to be further nerfed in the future.
As for the KV-8, not being able to faust it does not concern me, as that was almost always a suicide tactic anyways. My main concern with the KV-8 is that more often than not it completely kills a PGren squad with a single FT burst, even if the squad retreats immediately. Not being able to retreat upon meeting a hard counter is a serious problem that kinda breaks CoH's original concepts.
