Please do not add extra categories without permission. I removed the ground vs air troops awhile ago for a reason.
Also, as for adding new pages regarding new features. I've deleted the pages that are incomplete and do not follow format. If you are going to create a new page, at the very least have the format ready; not just a blank page with a paragraph.
The only page I have added is Scattershot I did my best to add some basic information that isn't stats from all the sneak peeks unlike people like User:Logikk (and other page that you have deleted, which are not made by me) in which I help fixed the formatting of that page using other existing pages.
Also may I formally requesting adding ground/air troop to heroes and the new siege? I did that because when I was editing Scattershot I was typing in the observation that each shell only damage one type of troops based on what it is targeting; so I figured heroes and the new siege should have a defined ground/air category because it matters even more now.
Lol, I only fixed Siege Barracks and Giga Inferno only because I was too tired and sleep through it as well, the next day when I woke up I got this warning.
As for ground/air troops category, I think using just "ground/air troops" is fine for the heroes as well because technically they are part of the troops. The first three siege machines already used the air/ground troops category, unless we creating a sub category of ground/air heroes and siege machines and put them in ground/air troops respectively, is that fine too?
I just don't want them to be put in the same category as "troops" as they are more special than that. And it would also make many other users want to add categories to the troops page, knowing the category exists. I'd rather completely remove the "troops" name and have one for heroes, and a completely other one for machines.
