>>54117186The issue with adding all the types is that one is always going to be left out with no weaknesses, and one on the list won't make sense.
You can have everything make sense by removing Rock however and just pairing it with Ground, but you'd have to remove resistances because they wouldn't make sense then. Unless you just straight up redid the entire types different from the game.
A good example, lets say:
Ground > Steel > Dragon > Bug > Grass
For instance, Ground destroys Buildings, Swords destroy Dragons, Dragons squash Bugs, and Bugs eat Grass. Pretty simplistic, makes sense.
Then you get into resistances, what you would have to do then, in this scenario would be:
Grass resists Dragon, Dragon resists Ground, Bug resists Steel, Steel resists Ice, Ground resists Fighting.
In this instance, you can make sense of some of them. A fighter can't hurt the ground, bugs invade buildings, a dragon flies above the ground, a building/weapon won't shatter from ice. But then you get to grass resisting dragon, there is no logical way for that to make sense, especially since most dragons are firebreathers.
And there are a couple of examples of these, going from these examples. For instance going around this circular logic from the earlier examples, poison would resist dark, ghost resists flying, etc.
There is no logical way to fix the Pokemon types in game without adding a new type or two to try and fix it for the spots that don't readily make sense, which may throw off the entire balance of the game. For the TCG, this just isn't possible, because its a weird number.
I will say that Fairy should be added back in, I know a lot of people had problems with it in terms of balance, but I think it'd be fine. Just add ground as well, then you have a total of 12 types and can work around things, or add another type to rework things slightly for that 12 total, just have to figure out which one wouldn't cause any color issues (Steel/Normal say hi).
