Playstyle vs mechanics counters

Just a quick discussion/tip -this is something that I have noticed about countering. IMO, there are two types of counters - playstyle counters and mechanical counters. Playstyle counters might be that kit >> engage - for example, ezreal is strong against leona because she is an engage support, and he is a kiter. A mechanic counter might be that kayle counters zed - it's not as much about their playstyles as it is that Kayle's ult is just so good against zed.

tx, love to here your thoughts!
