Thank you all for your replies. I have a 50 Elec/Elec/Elec Blaster. Since this poll and this post, I've made an Elec/EA Sent. I'm liking it so far, but it is still low level.
I've always liked draining End. One problem is that when I tried that using my blaster, I would often do Short Circuit, Power Sink, Die.
Since Sent is more surviveable, I might be able to drain without the 3rd step.
