I don't understand how a simple designed, low tiered set can be so popular.
Since I haven't heard of it until today, when I saw this particular set for the first time, I mistook it for some vague Christmas costume set that I somehow haven't seen around.
Maybe it's just like the Groundbreaker set, where you wearing it meant something. In this case, you were a beta tester.
But the Ignition set has no symbolism (is that right word to use at this time?) except to show that you play SK on a site I never heard of until today, just like the set itself.
So, what makes it so popular?
It's new gear, and people want it. That's all.
