Ships & Modules

t2 high damage ammo had this same drawback and CCP used the same wording in its description as I recall. A tengu/drake pilot before the removal should have seen this wording. And seen sig radius go to crap with furies mounted. It was not a stealthy number change.

And ,well, what else can it mean. Its not like caldari can have a worse em hole than that of 0 %.

Probably, but I doubt it'll be something you're exposed to early in the game and be relevant to ships and/or modules I use.

The op finally looked at the attributes of a module he's apparently used for more than a short while, and i doubt they'd skip using mwds on frigates completely.

Yes. While your prop mod is active, you have reduced effective agility. This is easy to test out in space.

Also, the mass penalty is an important part of the calculation to determine your mwd/ab speed. The calculation is something like this

Top MWD speed = (top base velocity) * { 1 + [ ( listed boost % on module ) * ( Thrust / ( Ship Mass + Mass Penalty ) ) ] }

An example of this is t1 and faction frigs (in particular the dramiel). They have much less mass than assault frigates and get a much higher speed boost from prop mods. This is also why adding armor plates reduces the mwd speed without reducing the base speed. This also explains why cruisers get mwd-sized speed boosts from 100mn ABs. People often ignore the mass of ships when looking at their stats, but you can get some good insight comparing the masses of ships in the same class.
