Most of my counter arguements come from a 2v2/3v3/4v4 standpoint and do not necessarily relate to 1v1 balance.
I don't see why people complain so much about the KT as a mainly Axis and Okw player lately I find compared to the other choices, it's bad for the cost, as if it comes across any kind of IS2 or Medium allied blob back by Jacksons it just dies, especially if it gets an unlucky Engine crit or crew Shock.
It's speed is slow and it has low range, it's damage is ok at best until you get vet 3 or above.
Again people who whine about Stuka, ok it's a set line but that line also has Scatter on it, so it can 1. Wreck EVERYTHING. or 2. Completely miss. - Also, spread shit out more!
It's like blobbing in to a katy strike after you hear it fire - no excuse.
Also find it funny people complain about Panthers MG's, they have to all be frontal facing at infantry and for a decent length of time unless you're in red cover, it's not like it's a squad wipe machine.
However I agree with almost all of the other points made already in this thread. Especially the Tech trees and call in tech.
