Which clan's got the best icons? Here's my top 3:
#3: HAWKS - clean but lots of detail and pops out
#2: Discovery - simple, distinctive, bright, pretty
#1: Icelandic Turtles - you take one look and you think "oh, that's an Icelandic Turtle." Can't say that about any other clan logo.
Honorable Mention: Relentless Hordes of Shambling Corps - 90s arcade vibe
