I think a lot of people would appreciate the ability to modify the graphical intensity of the game --
Whenever someone spams a pulsar, the explosions can become... unappealing to sensitive eyes. I realize there is a warning for epilepsy, but not everyone has that. Some of us are just not excited by weapon fire spam.
In Lockdown, I think the pulsar would be better if it had a 2-shot restriction like the alchemers do rather than the 3-shot because of its shock ability. This may create some angry responses from the less-enthusiastic players, but I think it will help improve the overall quality of gameplay.
EDIT: In addition, Gran Faust/Divine Avenger should get a slight damage debuff in Lockdown -- they are fine in regular gameplay, but PVP needs to have nerfs on these two weapons as well as the 5-star Pulsar guns.
Bumping just once to express the recent edit I made.
