I'm sorry if I'm being a pest by just posting complaints/criticism repeatedly like this...
Is it just me or is the Mini-Nuke spectacularly overpowered? I don't think I'm supposed to be able to
effortlessly kill groups of 50+ enemies by just clinging to a wall and firing a couple of shots into the crowd (my HP is so low because I was trying not to resort to the Mini Nuke at first). Considering the blast radius's size and lack of self-damage, having a base power of 67 is kinda insane. That's something I'd expect to get partway into hardmode, not as soon as I reach Hell. If anything, that would make more sense for the Vaporizer to have that much damage, given its status as a sniper rifle. I think maybe the Mini-Nuke needs a third tier with its current stats, and the Gravity Bomb's stats should be given to the Mini Nuke, with a nerf to the Gravity Bomb to accommodate. This is just my two cents, maybe I'm entirely wrong in my assessment of the situation.
What is the Guardian Ambidextrous Axe trying to accomplish? Is it meant for combat or utility? By the time you get it, it's outclassed in both fields, entirely because it takes upwards of a full second to swing. I think that either it needs way more damage to be worth using as a weapon (it has a lower base than the Mini Nuke, even!), the ability to chop down trees in one chop to be worth using as an axe, or a less severely slow speed to be better at both. With a melee-oriented armor set, I can oneshot two zombies with the Blitz Cannon in the same amount of time it takes to swing the axe once and fail to oneshot either of them. This isn't hyperbole, this is an actual example from gameplay.
