Well duh, of course there's strategy to Dominion, but it doesn't go anywhere NEARLY as slow as Summoner's Rift.
For example, Blitzcrank roaming the map with anyone who has good burst DPS is a pretty powerful combination, and if anyone plays Blitz, a good idea would be discussing this plan - making sure he knows to stick with someone, and to find someone if he loses his partner. Sure, he's strong on his own, but Blitz really makes skirmishes dangerous, whatwith all his CC.
