doesnt really have the sense of team work does it? its more like 5 peope randomly capping flags doing their own thing , to me its about as boring as playing a custom match vs bots on your own.
It can feel like team work when we play as 5 on mumble but mostly I agree, it's quite headless chickeny. Part of the problem being that if you're not in an arranged 5 then communicating as a team is really difficult in Dom as you can't afford typing commands to people as that just gets you caught. People also find themselves defending a point too much leaving the team a man down for fights which is also really annoying.
Summoners Rift is just a much better map for people who want tactics and strategic game play. I don't mind playing dominion as the games are over quickly but if I want a game where I feel like I'm doing something I'll play SR.
