I played most of the Beta with two LW characters and had no difficulty reaching level 7 with only a couple team wipes. It's a trait that is very punishing of mistakes in your build, but properly executed it makes your characters very hard to kill (I found the mobility provided by the extra AP crucial). I suspect the trait is less effective for characters who cannot engage targets from range. It may be a severe drawback late game but as I've not progressed that far I can't speak to that.
If people do think it needs some kind of buff, post your ideas for Larian to see. Perhaps they will consider it.
