The new Level 75 skills were studied by everyone. It didn't matter what skill level one was at. In the end, it was still something new. Those at a higher skill level would use it very effectively. Those at a lower skill level would easily get their attacks neutralized. While at the pro level, it was no longer as simple as if the timing was right or wrong, better or worse. What mattered was suitability. Every player had their own style. Every character had different stats. As a result, how a skill was used would be different. The variances from standard combos came from these differences. Pro players would make adjustments to these combos depending on their strengths and their style.
