It was meant to be temporary: start a one man clan to solo titans, then rejoin a regular clan... But months later I'm still solo. Why? Because you get faster match-ups and fight more people.
Arena is my favorite part of the game and I see posts about the lack of players online, but have you considered that you don't fight clan members?
If 350 people are online, they wont all be your same level, and many at your level will be in your clan. In other words, if 30 of those 250 happen to be good match-ups, those few you're losing to your clan start to make a difference, and it gets more noticeable the higher you rank up.
I miss clan loot boxes but for me, its not worth the reduction in arena speed and veriaty—at least not for a while longer. Just sharing this in case some of you are sick of fighting the same person over and over.
7000 lets gooooooo!
Pro tip: If you hate fighting someone, join their clan, lolz.
