If this has already been stated let me say sorry for adding another one.

1)The possibility to compare and contrast gear when you have one selected and hover over a different one and it shows both so you can see a little easier what is better instead of the current click look unclick look at next.

2)Change the amount of Dreadnoughts in a match at this rate we'd purge all of them from the Death Guard.

3) hopefully a few more Nurgle enemy types soon since there are so many the Drones both biological and Mechanical.
