Great day today.
Firstly, secondary account with light team and Valkyrie is ready to roll.

The only problem with light teams is the lack of friends with light leaders. On the plus side, this team's recovery is godly.
Secondly, I cleared Hera on my main.

Went full retard and missed gems elimination twice (thus respawned twice), but otherwise there was no real problem after stage one. Basically, Hera's stage is a gamble for a good first stage (for sturdy teams anyway), and once you are done you can just arrange gems and use monster skills to help clear the stage. Nets me a -1 gem since I get 1 free for clearing it first time, but 1 gem's cheap for a very useful god.
Now if you excuse me, I'll be taking a rest after that 3 hours battle.
