Boxing the meta 4 man

[Cmoidudu]

I'd like to change the main DPS into something else (since I'll probably never get that ancient Twister Sword anyway). He needs to be a a melee DPS, preferably with aoe damage. Also he needs to use a one-click-spam skill, because using 2 skills (like the Wizard / Arcane Orb template) will not fit well in the team. And I'd like to avoid using pets because it slows creature packing for aoe DPS.

I was thinking of a WD / Firebats template... We don't see a lot of them around, but I believe it's because they are very weak. Of course with the amount of defensive skills generated by the team, it will be another matter, also he can benefit from the globe generation because of the "Gruesome Feast" passive which will permanently increase his DPS by a lot.

I'm thinking of this template, he should be able to spam Firebats with a lot of damage enhancements, including 75-100% increase from Ring of Emptiness, and Haunt + Locust Swarm + Soul Harvest used as spirit generators. Mana regeneration should be superior to mana consumption, even without Reaper's Wrap bracers, and even with "Pierce the Veil" passive.

Also using a Razor Stop belt should be nice but I don't know how the damage from the explosions will be increased.

Any idea about his, or other templates ?
