m36 cant deal decent damage to a king tiger frontal armor need to flank...
Yes, and while flanking you usually can't flank and utilize the M36's good range because the farther you are from the KT the more there will be shot blockers and LOS blockers in the way. In theory jacksons are awesome, in real situations not to the same extent.
What comes to the strategy diversity, 3 to 4 different strats would be a dream come true in 1v1 games - mostly 1v1 is just spam / blob grens, rifles, use whatever is the OP thing to do at that time and not deviating from it. Ppl who play this game make it very boring at the same time
