Good lord. Um...since ED, this is pretty much outdated now.
That, and the fact that I've seen SEVERAL elec/elec that could render entire groups totally impotent about every other group indicates that either your info is dated, or just not that well thought out. I've never personally used it, but my best friend took his to fifty with very little problem. LOVED it, in fact. He also almost never ran out of end, on a side note. Seriously, with us now being able to slot only thrice, you might like to rethink your post. Points for effort though
