No because tournaments now use a faction ban system because generally speaking maps tend to have some faction that has a solid advantage. For example, Theta is a solid Aeon map. Crossfire is a solid Seraphim map. If you ban the objectively dominant faction the other 3 are typically closer to one another.
You see Seraphim banned quite a lot, but even when it isn't it is often picked.
Here is a thread with some analysis of the faction veto system:

Here is the thread recognizing the problem:

"First, to recognize that this is in fact a problem, I took a look at the tournament games during the two days of LotS, and what I found was that only 18% of the games in the entire two-day span had nonmirrored games. That's 17 nonmirrored matches out of 82. Once you refine the range to only look at the RO8 games, it falls to 5%. The semifinal and final? 0%. That's a problem."
