I thought freakazoid was pretty average but it's still a bit odd to see him completely out of the competitive scene (more or less) despite being a free agent for such a long time
I only recognise the korean and some of the T2 american players. But wtf how are some of these Korean free agents without contracts. Some of them are legit insane. That's sad. Literally there is a team you could easily create that could be close to tier 1 with just those free agents.
I think Pheonix is a really good free agent. I also thing Sage and Jett are easy to use at a high level in terms of free agents. Brimstone is meh and Sova is hard to use.
