First, I don't think 7 min is as bad as 6 min, because fewer matchups regularly go into the 6 min range.
That being said, the decision to change it to 7 appears to me to be capricious and ineffectual. The stated reason for changing it is to save tournament time. Will this actually happen? I have my doubts. Okay, you MIGHT save 1 minute, maybe, in the strange case that a regular (non-campy) match for whatever reason goes to the time limit. However, the incentive for campy matches to wait the full time (I'm thinking samus vs. Peach on a big stage, or whatever) increases. My thoughts are that the bad outweighs the good.
Clearly, the TO can do whatever he wants. He can even make it all pokeballs on very high. But we have standard rulesets for a reason; these things have been thought out. I'm fine with 7min and think that Eric should be fine, too, but the decision to make it thus seems arbitrary and misguided.
Look forward to seeing you guys anyway :D
