I love this game!

Getting back to my point, I have gone through a lot of posts and I have a lot of confusions.

I have about 1500 ironite. 300 tropper badgets and about 1000 arena coins.

I can unlock some 3-4 toons that are 5* from the store through 300 tropper coins. I was wondering if any of them are worth it

Options are: tropper eddie, lady azov, bastion, warlord, eternity eddie etc. I have heards lots of people mention about lilith, is she great?

What all should I do, farming etc? Arena is challenigng now, story will end soon, limited time events?

How do people auto farm?
