The striker shield seems to give too much of a bonus to sword damage. It's pretty typical for me to get one-shotted by DA users with the striker shield(and yes, i do have elemental defense).
Meanwhile i'm over here with my Callahan, taking 4-6 shots to kill anyone. The only bonus i get is a small attack speed increase with the recon shield. Attack speed isn't even really important in Lockdown, not nearly as important as accuracy and power is.
thoughg its not mention the striker has a hp reduction too.
but still, guns are a bit underpowered in here, mabey add a slight damage increase in the recon mix.
