New Dark Troop: Orc Drummer (Ground based rager)

(Don't know if this has been suggested before so sorry if it has, couldn't find it in the prohibited topics list.)

Suggestion for a new dark troop, probably to be at lvl 8 dark barracks (as it is essentially the dark equivalent to the healer)

The orc drummer would be a ground troop that has a similar effect to the rage spell (no speed boost, smaller radius). It would move amongst your army to the densest area of troops (with the same targeting mechanics as how a healer targets), and have a damage increase bonus to nearby troops (although not nearly as strong as a rage spell).

I haven't given much thought to statistics/balancing so don't criticise the idea based on these figures, but my rough suggestion would be:

Unit:
- 25 capacity
- 425-700 dark elixir
- 600-1000HP
- movement speed same as giants
- 0 damage

Rage effect:
- 30% - 65% damage increase
- no speed increase
- 2 tile radius
