Reworking The Crystal Scar Into Shurima
Ever since the Shurima update, its subsequent lore updates to those desert champions and Ascension, I've wondered if the Crystal Scar would eventually be reworked as a location in Shurima. Since the Crystal Scar was, and possibly still, is Skarner's home (who now lives in Shurima as a matter of fact), it only seems right, doesn't it? The new Rift has been out for some time now, and though the Crystal Scar doesn't receive as much play as the Rift, maybe a good rework is what it needs; sometimes I myself can't bring myself to play a champion if its visuals are outdated (I'm sorry, but I said it).
Maybe the Crystal Scar could even be the ruins of Shurima's capital, still devastated by Xerath's battle with Nasus and Renekton.

as for why no one plays it, I think its more that there isn't an official championship for that mode, so no one really thinks much of it since it isn't the "main" mode. A great way to fix that is for worlds to host a championship for each mode with a trophy for each, kind of like the Olympics has multiple events.
