This is my take on consumable usage.
*First and foremost, I'd like to address the fact that I've been anti-consumable on retail for years, and I had a really difficult time respecting players that would use them on a regular basis.*
With that said, classic is an entirely different community & atmosphere. Consumables are part of the game, and you are encouraged to take advantage of them throughout your entire leveling process. On retail, resource management isnt an issue whatsoever. In classic, you are pretty much forced to stocking up on both mana/health potions. Which I believe we all can agree on, is completely fair, correct? The controversy here lies within bombs, swiftness potions, and sleep dust.
I personally, have used speed potions on classic. It isnt often I do so, and when I do use them, it isnt for any sort of compensation. It's literally just to get to Point A to Point B at a faster rate. Bombs and sleep dust aren't something that I've ever picked up. I really do see both sides of the fence on this matter, but in PUG games, I really dont care. Of course I find it scummy of someone to speed pot to me 2-3 times a game, hit me with bombs off CD, or sleep dust me as I cross mid...but this thread is titled "consumables in general" which more so is directed towards PUG games, not organized. With that said, why must we have a conversation on this? Player X agrees with consumable usage, while Players Y & Z dont; Does this mean we will officially come to terms and blacklist consumables because the majority dislikes them in PUGs? Because that will NEVER work.
All we can do is control usage in organized games, abide by an agreed ruleset distributed by both parties (not the entire XPOFF community) and shame those that break them publicly on a thread, much like what happened to Mvq.
