It really was... Mostly because you never knew what you would go up against or what your team would really be composed of. Back then the meta wasn't really enforced hard like it is today. Lanes were completely random at one point. Bot and top was a random 2v2 mix of everything and ADC's and Junglers weren't mandatory at all really (until AD's started going mid). The 0 cs support role wasn't really a thing yet because stuff like Taric and Sion roamed (oh god roam sion D:). There was still a meta but it wasn't really enforced.
