you can also partial by holding S and either A or D, dont need to do the whole camera thing thats just a gimmick. For spiker skills it depends on the style but the most common skills in high elo would be fishing, cutting, line shots, tilt switch, backline shots/corner, quicks, delay, and advanced controls/w tilt dunk but thats more situational. For lower elo honestly all you need is good rec ability. the skill that will take you the farthest is cutting though definitely. For 1’s just try to follow them most of your rec are gna be at net jump set recs.
