Why I think that? Its because how he looks.
In Dow1 we have as a Big Mek a big, seemingly fat Orc with Swiss Knife - like tool.
In Dow2 we have as a Big Mek a low profile Orc with a Shoota.
On the other hand in Dow3 we have a Big Mek in Mega Armour called Wazmakka which is cool, because same Big Mek's model is in Table Top.
Of course I noticed something interesting. In two previous Dows Big Mek had a ability to repair building and vehicles, while in Dow 3 Wazmakka doesn't have. Is it is something thats intended, because it would give him too much utility? And what are your thoughts?
For clarity saw gameplay videos and played Open Beta, so I know what his abilities are.
