Looking at the 5 upcoming champions after Jayce have gotten me excited.
Take a look for yourself!
PS: I see a new stealth champ that might be released right after stealth rework!
Edit: We might be having either a double release upcoming or another lore related back to back release. Champions in question are DarkSov and Diana.
