I'm not sure if Blizzard reads these forums but this is simply to add more ammunition against this subject.
They should have added Valor point weapons to the game. I've been grinding daily quests which I HATE every week just to get the 3 elder tokens for a bonus roll on loot. I've done this for the 3 months or however long the LFDR has been open in MoP.
If I look at all my Elegon kills from LFR, I have 8 kills. 4 Amber shaper and 6 Sha of Fear. 18 rolls on bosses which drop weapons not counting using Elder charms and I've gotten nothing. Now if you also add the 3 charms I've used only on bosses which drop weapons almost every time, that's a lot of chances at getting a weapon, yet still nothing.
So I've just went and grinded dailies which I hate, just for an extra chance at getting a weapon yet even after all these rolls I've done on weapon dropping bosses, I've still had no weapon.
I can't think of any good reason there's no buyable weapons in MoP for Valor points. Yes, I am well aware that they typically give some classes the best increase in DPS however there's no good reason I can think of for completely omitting them when they can be introduced at a fairly high price (3500 or something) for people that want to grind the points.
I'm well aware it is random and extra charms don't guarantee loot, so there's no point bringing it up as I've seen a lot of you do in similar threads. Randomness is fine but I should have the option to buy an item if I've been grinding monotonous, mind numbing, boring, repetitive daily quests in the vain hope that I might actually get a weapon this week, only to be dissapointed time and time again. If I've done something so many times and I still don't even have an option to buy a weapon with all the Valor I've grinded which is another grind anyway, it's incredibly frustrating.
