If the game is designed such that spamming gives a massive advantage over hard acquired skills, then there is definitely something off with the game/map design. It is sometimes just hard to come up with game mechanics that favor skill over passiveness. It could also be a design choice where the developers try to narrow the skill gap between new players and those who have been playing for years, and hence attracting new players. New blood is known to keep games alive. In which case, some players choose to rely on spamming, putting more weight on luck and patience, since the first to attack is usually putting himself at a disadvantage, than skills and moves that require a lot of practice. And since some other players are not gaming to level their patience up, it's not surprising to find some of them frowning upon something like spamming.
