My idea which i thought might be interesting to spice things up in alliance, make it more fun and challenging if you’re bored:
Split up in random teams for example 2v2, 3v3 or go 1v1 on next titan. Most dmg in total for team or solo = ticket to next round. Single elimination principle. Fight until one team/player takes titan slayer name.
Items, levelups and other stuff is for you to decide.
Let me know what you think, good luck.
