I know from experience that the names of things matter a great deal to a significant portion of players. Final Fantasy has a lot of sacred cows to it, and the most die-hard fans hold this stuff pretty close to their chest.
It may not matter to you if Riot Blade is a crappy ability, but when FF6 came out it was my favorite game for months and months. You better believe seeing Riot Blade trigger made me quite excited, and this nostalgia still burns in me even decades later. The same is true of others in my age demographics, who happen to also be the target age demographic for MMORPGs.
