I need to farm IP, sick of normals for now. Elise seems strong. Do I just mimick what she does in real games? I've played dominion like twice so..
Anyway, here's a nice introduction to dominion. It's kinda outdated, particularly in terms of the bans (especially since draft pick is essentially dead), but the main points still hold. http://na.leagueoflegends.com/board/showthread.php?t=1544811
As for Elise in particular, I don't play her personally, but the ones I see generally rush a BFT with sorc boots. Build according to situation afterwards. Abyssal works well, especially if you need MR. Glacial (into an eventual iceborn) or wooglet's for armor, depending on whether you need more poke or straight damage. Lichbane or void staff for more damage later. Rylai if you need health. Rushing a RoA first could work if you desperately need sustain for bot-lane.
Elise works well for both bot and top, so go nuts and have fun.
