When people whine and moan about Link's (or any character's) projectiles. These people seem to think that because they can't figure out a way around my strategy, I somehow have to stop using the strategy. "Spam" is just a word for the butthurt.
Story time: I have been in countless matches against Fox players who, rather than shining my arrows, continuously ate my arrows and up smashes until he (I assumed) had a hissy fit and jumped off the edge, giving me an easy win. Or other matches against Foxes who depend on the laser for poke damage, and I literally walk towards, eating the lasers, and Up Smash, Up B, repeat.
All arrogance aside, the point is this; no, it's not "spamming", no, it's not "cheap", it's just as viable a strategy as any other, with strengths and weaknesses. You not being able to find a way around it is not a testament to how terrible the strategy is, it's arguably a testament to how good the strategy is. And imploring someone to stop using a strategy because you can't beat it is absolutely pathetic and, frankly, unsportsmanlike.
Special mention to the folks complaining about excessive rolling. How dare someone dodge your attacks, right? Get a clue. QQ moar. Have a terrific day.
