It's a melee, if you allow someone to get close enough to use it effectively on you then you deserved to get owned. Play smart.
As for spar, I haven't checked it yet. Does losing the spar affect you negatively? Is there a reward for winning? If no, then again, it is a for fun activity, consider it a luxury.
Concerning the price, there is pretty much still nothing to buy at this point. You could get the sword in a day without packs. I see no problem with things being a little high in price because people are just stockpiling money anyways after having bought all the guns.
Also, Imprint, I do not know what it is you have against iZone, but it seems you have said nothing but negativity towards it. If there is something bugging you, feel free to message me.
