Not too exciting, I know, but this is one of the most unbalanced games I've ever played, but it has lots of potential, so I'm willing to put time into it.
Here I'm going to point out several problems and possible fixes.
The Rifle is the best weapon in the game by a lot. What problem does this cause? It makes it harder to play the SMG and near impossible to play the shotgun, because the game is a giant sniper fest. You run into the open, boom headshot. You fire at someone, by the time you've hit them enough to kill them with the SMG you've already been killed one by a headshot, and if you fire from long range with the shotgun it's useless.
So what do I propose? Well, it's a difficult issue, you could buff the SMG and shotgun, or you could buff the shotgun and nerf the Rifle. Those are practical fixes. Some more work required solutions are adding handguns that have less ammo and damage, but supplement your weapons weakness, accuracy for the SMG, range for the shotgun, Something for suppressing fire such as a burst gun for the rifle, but that would again require either nurfing the rifle or buffing the other weapons. Alternatively, you could make it so you could switch between either two or all three weapons during the match without dying.
Which brings me to the other issue, building.
You can build relatively easily in this game, but if there's any enemies nearby i.e. usually, you'll get killed before you can dig a hole or place anything.
Solutions? No idea, here's a few ideas, but nothing really respectable. On is while you aren't holding a weapon you could be immune from headshots, and be able to take a bit more damage. Or alternatively, you could have spades break blocks instantaneously, and have guns break blocks slower.
Which brings me to the last prominent problem, map sizes. The problem with this is that most maps are so large that the SMG and shotgun are almost obsolete since you need to either be at close range or using an extremely accurate weapon. I know tat this is the fault of the map maker, not the creator of the game, but it's still a major problem.
Solutions are either a map size limit, a lesser tendency to giant maps in the community, or one of two things I've p reposed for previous problems, which were, Buffed SMG and shotgun, supporting side arms, or the ability to switch in the middle of battle.
Thank you for reading.
