because both teams experience that moment of which team and which champ is going to initiate. Jax, naut, zac offer good momentary cc whether peeling or engaging. A problem is depending on the fluidity of the motion of the team, you have ppl who hang back those crucial seconds that could be used for repositioning waiting for what they think their window of opportunity to atk is. In that moment, when you could be using those other team mates as skill blockers, absorbers, who gives a fuck, they have the stats not u, you end up with a tank in your face basically saying oh well that tank has a gap closer and cc, I am hopeless.. This is where I see the excuse either always being, no team follows up their tank or initiator, or both teams initiate and one team plays it right while the other turns back onto the enemy tank leaving that jax, zac or naut to fend for self with their back line. this is why supports like malz are a good handicap, they can catch that enemy initiator or tank and cc them for those crucial seconds if he hasn't already initiated as well. of course I don't recommend a malz ulting a tank but when you consider the positioning of the team member that has gotten "dove," they end up feet away from their team almost "caught out" while a team fight is taken place. this is something I just noticed as a sort of issue... putting responsibility on a support to support a team and not just that weak link who does get pursued by a tank or engager. champs who cant be responsible for most of the team playing it right and also supporting that part of the team playing the team fight wrong. again this is because of communication or lack thereof and the teams overall knowledge of how a team fight is supposed to play out.
