Lovely format you have, SSW.
I tested it small scale with a duel of bots of somewhat varying difficultly -- From the weakest, to the Nightmare.
With the use of weapons and energy, the balancer is a perfect fit. I don't have to run around changing weapons of varying damage and tiers to refill my energy.
As for health spawning and non-spawning, I'm not sure. When I tested it witht he help of that naughty cousin of mine, we discovered the flaw that any two people playing in a map that doesn't have a PlantBarrierWep and a good area of Big/Small WepEnergy will be at risk of being "Trolled" by more skilled or less skills players by repetitive use of the same weapons, including and not limited to:
All these weapons can end up ruining the duel experience given the situations and circumstances that may lead to the abuse of them. I suggest some form of amending to this, to see if it will fix this problem, as all these weapons can literally sap away health within 10 seconds of skillful use.
On that fact, it'd be normal for a Duel-Fool[Skilled Duelist] to refill and re-engage a target, but in the case they can't find health to do so, they may lose to people more often because of the inconvienence.
I didn't include Star Crash[Hugging], because most of the encounters I've had with that would have to happen at close proximity, and can be survived.
Also, I'm all for that Sphere Power-Up. What will be its use, and how will it be applied?
