Personally I can't find a reason to watch any AOE4 tournament, both competitively or atmospher wise.
Game related: Why would I watch a tournament if there is literally no micro potential except wololo conversion, no dancing archers of Liereyy, no Daut lure failures or no quick walls of Hera and Viper.
Interesting. Just wonder how people enjoyed watching AoE2 15 years ago where nowbody even heard about dodging balistics, quickwalls etc. In those days "good micro" meant standing on hills and focusing appropriate units. According to what you wrote it sounds boring as hell, doesn't it?
