Another type chart change (semi-joking?)
As we currently have it, steel had been significantly nerfed in gen 6, losing resistances to dark and ghost, causing many formerly good mons to plummet in the tiering scale (e.g. Metagross). What if we adjusted the type chart to help balance out this nerf? In this case, I'd suggest making steel neutral to fire both ways. It kind of makes sense, since most steel alloys have melting points around 1500ºC, high enough to also melt most rocks (a typical temperature for lava is ~1200ºC)
(On the other hand, some metals have quite low melting points, like lead at 327ºC, indium at 157ºC, cesium and gallium around room temperature, and mercury at -39ºC; maybe these were the reason for making steel weak to fire in the type chart.)
If this change was made, it would somewhat improve bug/steel and ice/steel defensively by getting rid of a common 4x weakness, probably seeing more usage for Scizor and Alolan Sandslash, maybe even causing the latter to move up to genuine viability in RU or outside weather teams.
Lvl 255 252 SpA Chandelure Fire Blast vs. Lvl 255 252 HP / 252 SpD Sandslash-Alola: 998-1176 (112.5 - 132.5%). (this is only a 2x weakness in this case) Almost no one runs full defensive on Alolan Sandslash though, I think. Oof.
Would you agree with making this change?
