Terrible teamwork? --> "relax, it's Dominion"
Suicidal 1x all atempts? --> "relax, it's Dominion"
Nonsense champion composition? --> "relax, it's Dominion"
It pisses me off when people try justify their poor decisions saying "relax, it's Dominion". This assertion is like a noob certification. Just because the map is Dominion it doesn't mean that there is no strategy in it. If you do whatever you want without thinking, you may end up screwing everybody's game.
Another assert some (unskilled) players say to justify their lack of skills and knowledge about the map is "whatever if we lose, Dominion is just about fun". I agree Dominion is about fun, actually all maps are about fun. But we have more fun when teamwork is great, champion pick synergizes and the fights are strategicaly arranged, rather than losing the match because one or two unskilled players don't know how to play this map and think there is nothing to be learnt.
So here is a message to all of those who say "relax, it's Dominion": Dominion is about fun, but just like the other maps, it has its own strategy and meta, it demands teamwork and it can be as challenging as Summoner's Rift, if you play it right. If you think Dominion is a map for doing whatever you want without thinking, then you should go read some tutorial before playing, because you are probably screwing everyone's game in every match you play.
