I genuinely believe this game would be well balanced and fair in most regards in general. Aside from a few weapons that could use better tweaking like the Goo Tuber, Flingza roller, and inkbrush, most can put up a great fight.
I would not keep harping on Ink Armor if I did not believe it was ruining the balance of Splatoon 2, and there is no denying it does. Coupled with the ping issues with Splatoon, and the very nature of the special, there is no way the game will be truly well balanced until it's fundamentally changed. Just making it take more points to activate is not enough.
The devs of Splatoon 2 made it a point to change specials to make them less game changing, make the more about support. Giving an entire team the means to easily wipe the other team is exactly what they wanted to eliminate. I can't believe in all their testing they did not think that having multiple ink armor users on one team can literally win any game, something no other special could do, in either game.
Here's hoping they really fix these issues, because right now skill has taken a back seat to using a broken special, this is especially true in ranked. Tri sloshers and N Zaps are as common as inklings in ranked matches, and they can easily turn the battle in their favor without any skill or strategy. This game won't have a competitive future if one strategy is so bulletproof.
