I personally agree with OldTrees, but only in principle - you shouldn't get points for doing a bad job. However, if this becomes reality, I consider it would be at the very least fair to add more possible tasks to choose from, as I would find it truely incorrect for a person to have a lower chance at becoming a Master because he isn't good at card design, which is totally unrelated to being a Master.
I totally disagree. In fact, no one should be better suited at making cards of an element than a master of that element. Why? Because being Master means that (in theory) you know what the problems/themes are with your element. Being able to put down ideas will show your level of understanding of what your element is & needs.
You would think so and maybe in theory you could find a reasoning that that is correct. However, in practice, this never happens. Best card designers are nearly never the best players and viceversa. For example, last time I saw his stash of cards, ET's cards could all fill in 1 screenshots. How many Tournament wins does OldTrees have? Does it seem like majofa, kev and blonde have tons of card ideas? Does simply designing some cards proves you have the metagame understanding to do well in War (because really, all Masters do is War)? Kael Hate was the first Card Curator if I recall correctly, coming up with tons of inventive card ideas, but when he was in War, Darkness didn't really do exactly the greatest impression, they didn't dominate because of the so-called superior game understanding of their Master.
The point is, even if you know what your element is missing you can still make a bad card maybe simply because balancing card ideas isn't your strongest point, you just happened to have a bad idea or you cannot think at something to sensibely fill the blank while still fitting the theme (how should one solve the no-CC issue of Light when the theme is clearly Light doing its' thing better than the opponent ending up simply overwhelming with brute force?). If you want another example, look at SoP. Out of everybody, you would expect Zanzarino to know the theme of the elements better than everybody and Water has nice stalling and CC - but he is apparently out of touch with the current PvP metagame where speed is everything - in a vacuum, SoP is a good idea, but given the current metagame there is no way it is going to be used competitively in its current state.
