The shipmaster scout mine meta. Still my favorite season.
Jackrabbits taking down bases.

This, because who thought that was a good idea.
Serina every game
Triple Johnson Mech rush. Yuck.
Pre season Rolling Eco with Jackrabbits killing everything.
Probably the Forge-era, because why/who asked for it/how.
But, the Kinsano T1 turret drop and Serina base-blocks were also a special time
I reckon the Jerome meta, 6 mechs going back and fourth. With the occasional atriox chosen in the mix. The locust meta was crazy too, when they were an anti everything unit…
Anders pre-season Sentinels 
The few day long marine meta was wacky, I lost too many games to just hero + marines the whole game.
The Serina rushing straight to your base and freezing your turrets so that she can do whatever she wants without you fighting back at the 1 second mark meta was pretty strange.
and cool!
I think the Jack Rabbits were quite ridiculous, but i wasn’t around at the time that was a thing so I can’t rank it, i can say that the forge era was quite bad. But in my opinion, i think the Jerome Mantis was just awful. All games during that time you had everyone going the same leader and the game would end in like 3 minutes or less. I rush so I’m used to only 7-15 minute games but only 3 minutes was way too short. And to top it all off if you had the balls to go any other leader, you’d get destroyed. Which only tempted more people into playing Jerome. It was Jerome or be Jerome’d.
anders at the start of it all when her Sentinels could just kill everything and take down bases without any upgrades at the start of the game.
Forgehog was already powerful and 300% buff damage as well increased radius was complete 
. If you built Forgehog, you had all the army you needed as he could wipe anything and everything in a heartbeat. So powerful even mid game was completely futile with no fighting chance whatsoever.
When everyone was building their hero regardless of their leader to the next season where I would see only a handful of people build them.
