I think there should be a limit on in element bans, at least for next year, Lets say in the air earth matchup, if earth banned Dragon, wyrm, and firefly, Air is stuck with UG and off element attackers. Same with earth if golems, dragons, and graboid were banned, you've got antlions and stalling as means to win.
Im glad to see this wasnt a major problem this trials but i can imagine it could get worse.
Aether without immortal, phase dragon or recluse
Darkness without vampire, dragon, and gargoyle.
