Quoted from you, you say the WC51 is OP and use the number of time it has been used during a tournament as an argument. By the same argument so are 5men grens.
The unit is OP but not because it has been used in a tournament, that is simply an indication and answer to those who claim that the commander is useless.
I am not sure why you keep bringing up the 5 men grenadiers, if in your opinion they are OP start a thread about. We can debate anything you like about them there but not in thread about a vehicle like the WC51.
You have no evidence that the WC51 is OP other than your vision of the unit. You can throw list every abilities it had, that doesn't make them an argument.
Well it is not just me saying that is Op, it is a large portion of people posting here (including at lest one allied biased user. see post 102)
I am not sure what qualifies as "evidence" in your eyes but the abilities the unit comes with is actually an argument.
This debate seem to have taken a slippery road which I am not willing to follow. Feel free to present any arguments why in your opinion it is not OP instead of playing the "you said" game.
