Yeah that makes sense now that you say that, the frustration angle. I always just thought it was unfair, especially with how strong roll-dodging in smash 4 is, that someone could just ko and run the whole time, but 6 minutes is at least better than the dumb 2 minutes online. If you fall behind early in a stock match, you know you can play patient, try and whittle them down and get even with them. In time, if you're down you have to press and it can lead to mistakes if it's not your style. I just feel it punishes players who prefer to wear down their opponents rather than be aggressive. Not that I blame you in this situation, sounds like you were giving it right back to them, lol. I just never liked time much.
Take time away and it punishes aggression to an absurd degree. It doesn't make a lot of sense at the level of little local events, but those follow the rules of the big tournaments generally, and the big tournaments can have some respectable prize money on the line. If you could win a few thousand dollars for little more than being able to stay focused for a long time while other people get sleepy, wouldn't you? Plus the defensive strategy just appeals to some people, I'm the kind of fighting game player who...well, sucks, but I alternate between sucking at being very aggressive and sucking at using the most tedious tactics imaginable. It's fun to basically just sit there and watch people do stupid things because they aren't patient enough.
How does it punish aggression? If there's no time, it's not like there's something keeping a player who wants to be aggressive from doing so. Aggressiveness doesn't always equal mistakes if a player knows how to do what they want to do. Whereas if there is time, then it does keep a player who wants to be patient from doing so (Admittedly this is only if they go down by a significant margin, or late enough in the round they need to get moving), mistakes are borne in this case from a player having to play outside of their style. I simply see stock as less restrictive than time. And yes I am definitely biased, as I fall into the defensive category, and I certainly don't have tournament level experience, what I'm saying is merely my opinion. ---
