The current reward system for the Triple Triad tournament is insane, and needs to be changed. The tournament rules are also insane, but other posts have covered that more than adequately, so I'm just going to focus on the rewards.
1. Including functional rewards as card tournament rewards is a terrible idea.
Having functional, usable rewards for a card tournament means that the winners of previous tournaments will have an advantage over other players, making them more likely to win in the future. While the stats on Lightning, for example, are not great, presumably there will be some future collection size where unlimited 4-star decks are unlocked, and tournament winners (especially multiple card winners) will have an advantage reaching that tier.
In CCG tournaments, cards with unique functionality are virtually never given as tournament rewards. If cards with unique functionality at the top power tier in Magic: the Gathering were given out as tournament rewards, there would be a massive outcry from the player base, and the player base for Triple Triad should react the same way.
2. The Lightning card, and other tournament top three reward cards, are far too rare.
I'm fine with rare cards and hard-to-get cards. Raubahn was a chore, but satisfying to finally get. Cloud and the Sultana are - as other threads in this forum have covered - overpriced, but at least they have an obvious "progress meter". I haven't gotten lucky yet on Bartz or Terra. But ultimately, all of these rare, hard-to-get cards seem fine to me.
On the other hand, the Lightning card is currently so rare that it's actually quite possibly the most exclusive single item in the entire game at the moment. And that's completely unreasonable for a minigame-exclusive reward. Here are some comparisons:
Here's some napkin math from Reddit regarding turn 13 clears: http://www.reddit.com/r/ffxiv/commen...entage_of_the/. The math in that thread estimates 14-24,000 players have cleared T13 as of about a month ago. Obviously there are a lot of assumptions, but that number feels like it's at least in the ballpark.
On the other hand, there are 62 FFXIV servers, so we know the exact number of Lightning cards in existence: 186. This means that a random FFXIV player is probably at least 100 times more likely to have beaten the hardest boss in the entire game than to have Lightning.
The website xivsoul.com is doing automated scraping of Lodestone for statistical purposes. According to that site, over 7000 players own a fat cat, one of the most exclusive minions - and that only shows what the site has been able to scrape so far. A random FFXIV player is at least 30 times more likely to have a fat cat than to have Lightning.
Finally, for a throwback, here is some info on FFXI relic weapons in 2006: http://wiki.ffxiclopedia.org/wiki/Us...Stage_5_Relics. A FFXI player was about as likely to have a fully completed relic weapon in 2006 as a FFXIV player is to have a Lightning card.
As I said above, I'm fine with relatively rare, hard to get cards, but this is just ridiculous. When a card for a minigame - which was presumably added just to be a diversion - is rarer than all other content in the entire game, that is a design problem.
3. Concrete suggestions.
First, obviously, remove Lightning from the tournament top 3 rewards. The huge MGP payout is enough motivation for the tournament on its own. If you really need to have some special item as a carrot for the tournament, add something strictly cosmetic like the Cactpot top prize has. Personally, I'd like a top hat.
If you still want the cards to be attained through the tournament, there are a lot of options that are far less insane than the status quo. They could be participation rewards. They could be achievement rewards for participating in "The Manderville cup 5 times", or something similar. They could be rewards for finishing the tournament with a 15/15 record. There are a lot of options here that don't lead to these cards being rarer than 99.99% of all content in all MMOs ever.
Finally: In case this post comes off sounding like sour grapes, in my specific case it's not, unless it's sour grapes on behalf of my friends and fellow players, as I actually have Lightning. The fact is that the requirements for getting Lightning - and for getting Cecil, and presumably also Firion and Tidus - are crazy as hell, unfair to the huge majority of players, and should change.
