I don't care about what buffs or nerfs the Giga gets, as long as that ugly hitbox is changed, I'm cool. It's not because of the balancing that I want the hitbox. It's because a big hitbox is stupid, ugly, hard to use, and impractical.No. Giga should stay as 4x4x2, and have HE HG1 power, or it will become OP again. Giga is 16 blocks area, and HE cannon is 25. So compared in how much you can place on same area it will end up that Giga will be 1/3 more powerful if it has same power as HE HG1.
maybe just remove lower side blocks (space boxes) from Giga 4x4x2 so bottom will be 2x4 so we can put 1 block high weapons next to it, but keep upper level on 4x4 so no stacking of 2 high blocks is possible.
