Blitztigua it is. A long range (that's Magnus line territory) spread shot (blitz line territory) medium speed (Antigua territory) three shot (not quite a downgrade considering the spread) gun. First of all, this was designed as a cc weapon. Bomb territory. Rooting is no problem for any decent gunner. Also, it has more dps than an Antigua, an offensive sidearm, while you say it's a low damage barrier. That's contradictory and that's pulsar territory. Then you go and incorrectly identify the autoguns as cc weaponry when they are used mainly for three things: OHKOing Trojans one at a time, OHKOing Almirian crusaders one at a time, and blitzing Vana. That's comparing a FF charge to a BTB charge. Next, alchemers are not spam weapons. They are highly effective when aimed properly. Again, this is an inaccurate comparison

So what's a good comparison? Pulsar line v Burstgun. Both form a defensive wall. Both utilize knockback. Both are (supposedly) relatively low damage. The difference? Lag, knockback consistency, bullet spread. The only reason to use the Burstgun over a pulsar is if you're lagging.

Now don't get me wrong; the general idea is one I'll agree to. However, there is much to be tweaked. If you want an idea of a defensive barrier, go look at our broken shard bombs. I have ideas myself of switching the blitz needle and shard bombs around a little.

As for typing, pure normal with various cc statuses (stati?) sounds somewhat viable for a low damage weapon.
