Or, time warp can be changed so its not so OP and any stunlocks disabled, made into softerCC and made into critical hits only effects. Much easier to do then change the whole system.
Although making Source into a stat has some merit as a general idea... Maybe it could be tied to an attribute, which could give constitution something to do. That could keep the overall source points low. And serve as counterbalance for other attributes.
If its a consumable recharged by dead bodies as it is now... there is no end to it and almost no practical limits.
