So about Locket in the PBE
Here are the changes in the PBE as of right now
Locket of the Iron Solari Total Cost: 2800 --> 2750 Shielding Active: Shield power increased by 50%. ( 50 - 230 --> 75 - 345 ) Shielding Duration: Shield Duration goes from 5 --> 2
So the idea is to buff the shield, but at the cost of duration. That's good and all; it WILL protect my team from some heavy burst later in the game, but in a sustained fight, the shield will leave me wanting. So here's what I think would be a good idea.
Create two upgrade paths for the Locket.
Have one give a shield that lasts longer, but has a lower value. Have one give a shield that's shorter, but has a larger value.
That way, players have the option to opt for either a shield that works in a sustained fight, or a shield that protects against burst damage.
