Usually when I see something in roleplay that doesn't make sense, I inquire about it and see if I can get a logical explanation to what I was asking about. More than fifty percent of the time, I'll get an explanation that will clear things up for and I'll move on from there. But if I get an explanation that doesn't make sense, like in Timothy's case. I'll begin to question how these natural energy sources can be used without any repercussion to the user and vice-versa.
Everyone is iffy about regulations and rules, but had those same rules and regulations had not exist. You would've had Edo Tensei zombies doing Kage Bunshin or players making use of Hiraishin in one turn. Without these restrictions, you would have ungodly players abusing loopholes up to the point that they would literally suck the fun out of zone fighting.
In the end, I am certain if something becomes more of an issue to just one player. Some sort of rule or regulation will be proposed, but until then like Shadow said. If you don't like how they play, don't bother role-playing with them or just to work out something where you both Nerf each other down to an acceptable level.
Another thing that I don't get is the whole multiplier stack and the reason being is because we only have little canon knowledge to what ability that gives you this multiplier. It would be nice in the future to make a list, so we *all* know that your custom abilities give you an additional +/- multiplier.
