One thing I like about Dreadnought is the variety of different builds players have for the different ships. This changes in Legendary where it feels as if almost every player has the Assault Blink Warp on their corvette.
The problem I have with that besides that the variety decreases is that it feels like an overpowered and very easy module. Why wouldn't every player put that module into their ship when they only need to fly to an opponent, do a little damage if even that, push the button and then profit? You will probably even see me do it once I have my first T5 corvette.
In my opinion the module needs a downside during the use, like the corvette standing still a while before the warp happens or the player not being able to steer or fly up or down for a few seconds after the warp happens.
