I'm seeing a lot of people using sd's as a reason for 3 stocks. At some point, you have to just say "play better". There are techniques that will put you at risk if you try them in tournament. That also goes for recoveries and other things. We can't use poor execution as an excuse.
That's a good point. However, I would like to re-frame the "SD" argument into the more sensible "fluke" argument. SDing isn't the only way unearned momentum decides the winner.
Personally though, both 2 and 3 stocks have valid pros and cons, both rather equal in validity but the effects of both the variables themselves and the cost of trying to fix things later leads me to believe that 2-stocks are best for now.
But before we get into why, let me try to quantify the variables for both.
* = This pro can be considered a direct con of the other subject. I will not go into cons for this reason.
2-Stock Pros:
*Better logistically, and for time constraints. Probably the IDEAL stream time per match for commentating, since if it's a boring match, it won't be too long anyway. Better breaks for commentators to collect themselves and discuss the more easily digested matches.
-Most easily understood, and transitioned to for casual players due to for glory.
3-Stock Pros:
*Negates the effect of momentum, and rage.
As earlier stated, SDs are not the only mistakes that can be made that two-stock amplifies the effects of. The ability to adapt is also less rewarded in 2-stock, especially as things are with all this unfamiliar territory.
Furthermore, regardless of the intended use of "rage" it has become somewhat of a radical mechanic. Both for coming back, and maintaining a lead. I feel more stocks will lessen the effect of this radicalization, rather than amplify. Since the psychological impact of a 100+% diddy is far more threatening than a sub100% diddy that can't kill you with a single grab to upair. To the point that a better player will be forced to utilize an aggressive mindset to kill the diddy, but also even more non-committing if they're within the (now much lower) kill ranges of a grab.
Diddy is just a general example of how the neutral game changes with rage. I personally think it's a healthy interaction, but not one that should solely decide the match. And 3-stocks make these situations take up less percentage of a single match.
-Longer matches = No break in excitement or adrenaline for spectators, and players.
However, moving from 2 to 3 stocks would probably be an easier transition than 3 to 2, simply because 3 will always be more popular. Even if 3 ends up being an issue, it will obviously be harder to change twice than once. (From 2 stocks to 3, then from 3 to 2. Instead of just waiting until we know 2 stocks are flawed for sure)
