IvanBerni For a good mod there will always be a downside implemented. So the only building problem is it has to be a roof/underside weapon and has to have a blue beam. Other than that it's ordinary. For me I can create it in minutes without any spriting. In fact as it so happens I've a (far stretched) similar weapon for this kind of situation in the pipeline for about a year, but I haven't made any sprites yet and it's kind of different... actually it's a family of weapons. Now that walt has fixed half of the buffs, I could make it happen.
IvanBerni This is about Mass Effect mods, so saying "it can be done in vanilla" is not very constructive
Exactly, that's why the very first point of business is to justify why you need it if there are alternative options available. Then is whatever makes it different worth the effort (e.g. just color difference). You have to come up with good reasons especially when you don't do any of the work and put it on someone else's shoulders.
