I really don't know what the problem is with these kind of add-ons lol, some are actually useful and some are just funny to use
No objections to that, really. I'm really looking like a "stop having fun" guy, but I did enjoy guns tetrakaikimbo, in contrast to some other explosive bullet-hell weapons whose sole purpose was to crash the server if you didn't give the game a second to despawn all the crap you just launched.
It is possible to make a good addon which is "X but more" or "X but different",
Tablesalt's Gun Edits being an example for the latter. I don't think 10-seat vehicles will find themselves filled without a once-in-a-lifetime groupup event, though. The full potential of the eight seater magic carpets is already rare on its own.
