What's the maximum speed this mod could reach?

if that's in the mod store for 4m you have to buy it every time.

all the advice on this thread is correct. ads on a gold mod between 3-6. so max 27.

the only way you get great mods is by acquiring the ones that have the potential to be great. this one being speed is bonus. also a bonus that processors only have a defence primary, so the primary stat is also optimum. bottom line is even if it doesn't end up being an arena mod it will highly likely be useful for someone in your raid team.
