I see your point, but I think the difference is that we aren't talking about translations and romanizations. That is what we are using already (romanizations). For example Vegeta instead of Bejita or Vejita. Noone's using unnofficial romanizations, or straight romaji or kanji, which is why I get riled up when I see the "use english" argument. So I hope I didnt come off as contentious. It's just that I think people misuse the word translation. I dunno if you saw the old Mr. Satan/Hercule argument. Points on commonality were certainly worth discussing, but a number of the more vocal people were insisting that Mr. Satan was a Japanese phrase and Hercule it's translation. That isn't what translation is. The thing is, and I think a lot of people forget, is that English-language wiki is a language choice, not a subset of countries that we are allowed to write articles about. English wiki is worldwide, like every other wiki. Most other wikis get this too. Look at the French wiki. The French dub named Piccolo as Satan (Kami being god of earth, they figured his evil counterpart would be the devil) and then changed Mr. Satan to Hercule (that's where the name comes from). But the articles their were on Piccolo and Mr. Satan, making note that when adapted into french the names Satan and Hercule were used.
On attacks- those are likely going to be restructered soon anyway. As for why in most cases we used names from the Daizenshuu attack list, it is because that is the only comprehensive list that exists. I have tried... really hard... to work such a list based on the dub and even Viz manga. You can't. The manga doesn't cover every aspect of the series and misses some attacks, and Viz is weird with attacks (keeps some the same, half-translates some, translates some into Chinese). The dub has some that are the same or translations, some with names invented for the dub, some attacks misnamed as other existing attacks, some attacks with multiple names, and some attacks without names at all. For example, Piccolo's old signature move that you see in games more often now was the Bakurikimaha. You saw it when he attacked Raditz on the cliff. Gohan's first signature was the Masenko. According to the dub these two distinct techniques are the same move and called Masenko-ha. Goku's last ditch move is the Genki Dama and Yamcha's signature ki attack is the Sokidan. According to the dub they were both Spirit Bomb, and the Sokidan has also been renamed Spirit Ball. Tenshinhan's signature Kikoho has been called between dub, manga, and games the Tri Beam, Blast Cannon, Ki Blast Cannon, and Chi Kung Blast. It just gets confusing trying to keep track. And then there are moves that don't get named, like Freeza's Death Ball pr the Big Bang Attack. They get named as such now because of video games, which are translated from Japanese, which goes by the Daizenshuu list, so any attack that doesn't have a dub rename tends to be some form or translation of the original name (since no dub equivolent exists for them). 
 I really hoped that makes sense... its like 3 in the morning here, so if it didn't let me know and I'll clarify.
