I think bolt charge would suit this move better.
If you want a move called 'Bolt Rampage', make it an electric type version of outrage and thrash, since the name would suit this move better. Think about it, a pokemon rampaging about and destroying everything, sounds like a 2-3 turn confusing move like thrash and outrage. Whereas bolt charge sounds more simple, more like simply charging at the enemy, like megahorn simply charges at the target with a big and sharp horn.
You get me?
btw I recently changed my signature, whadda ya think?
