I was just wondering if there is something like that for dominion, on 5Vs5 he have solotop, jungler, solomid, support and AD carry on bot. So how about dominion?

4 top 1 bot.

mix of damage types.

^ Pretty much that.

You usually want a front line that won't collapse instantly, at least 1-2 sources of ranged damage, and a decent split between physical and magic damage so your enemies can't just itemize for 1 type of defense and screw your whole team.

There's wriggle room, though.

There's a lot more flexibility in what works.

Your comp needs the ability to both poke and dive depending on what is going on.

themed teams usually work best. stacking CC, or pulls, or frozen mallet/rylia's tends to do you good. everyone usually takes revive/garrison. rotate uses of revive and make sure it is off cooldown for end game if it looks close. bot is usually a top champ from SR. know what the buff does and get it with the most beneficial champ on the team. that about covers it.
