Not worth arguing. You don't provide anything, rather than pure rage for a unit described as underpowered by 80% of the community. You don't even mention if it was the oberkommando or wehrmacht version. Ignored for anger management sake.
Wikipedia's informations on tanks speeds:
Panther: 55 km/h (34 mph) (first models), 46 km/h (29 mph) (later models)
Sherman M4: 25 to 30 mph (40 to 48 km/h)
Definitely nonsense.
I am not raging I simply believe it is fine. Maybe 80% of the community that plays axis. It has really really great front armor it does great damage and it is hard to flank with shermans if the guy has a brain and uses the reverse. You have p4 tanks which is very close to the equal of a sherman. Why should the panther cost less and be out the same time as 1 sherman. Do the axis really need better armor than they already have?
Also as you can see I play mostly allies and I use a lot of shermans. What I hate going up against the most is not a Tiger of any form they are easily flanked and easily beatable what I have the most trouble with is a well driven panther just saying that is why I think it is fine. I think it is crazy when axis players make a bunch of tigers there like a fat kid with a sign on there back that says kick me most of the time unless there in a map like ettlebrook or something where it is very hard to flank tigers. Especially multiple panthers imo are very effective.
