So, to pose the question, in a competitive game, why does luck matter?
We're talking about a game of skill, where the reward for 'beating' luck is arguably the biggest reward to achieve. I've read how busted x is. How unfair y is. Why are we not building teams that work to corral these 'threats'? If something is dominating, but isn't a 100% lock (and please, unless the lock is 100% where your chance of winning is actually 0% don't say it is) you have a path to win.
When the meta game shifts, you work on playing it, or beating it. There are options that hinder Sand Veil, and clearly by reading everyone's posts here, Rain seems to be the dominating factor. Unless I'm mistaken Rain cancels Sand if it's on field after Sand has been activated, eliminating the boost Sand Veil gives. Which is just one way to work on beating Sand Veil.
The real issue I have here, is the common complaint of luck. Every game has an element of luck. Luck being 'an unknown and unpredictable phenomenon that leads to a favorable outcome, or its adverse.' When talking about games with evolving meta games, luck is going to be a factor. In this game we choose moves that do not have a 100% chance to hit. In other games you must shuffle your deck, or choose your pieces.
To combat these inconsistencies you produce effects that reduce their occurrence. While I understand in this testing we are looking to see how destructive Garchomp is on the meta game with Sand Veil, so we're actively looking see it's most used set up.
I would propose just unbanning it when BW2 is officially released so we can see how the meta shapes up. If it dominates for too long in too many official tournaments, ban it again. I understand that 'extreme luck based environments' are not fun to play in. But crying foul over luck with no adjustments isn't the best way to foster growth of the meta.
This isn't some plea to force unused pokemon into the OU tier, or playing janky cards to hope to beat the threat. There are excellent moves and abilities that make Sand Veil even or try and race it. And if you're seeking to play competitively trying these out instead of holding on to favorites or pets that get beaten over and over. That isn't healthy for the meta either.
If this jumbled, I apologize, but I've been giving this thought for sometime. The dearth of luck comments get to me.
