Dominion map seems quite small and it won't be "random" teamfight places i guess. All fights will be around the capture points and/or whatever big buff mob so i'm a bit wondering about teams going all wards and teleport spell to be ready to deny points totally.

Don't get me wrong, i like that idea, it could bring up good strategies and so but if it's too good (wards + teleport), i'm afraid it's going to be the core gameplay of Dominion map.

I don't even know if that's bad or not, but i realized that and had a concern about it..

Tell me if i'm wrong.

There are no wards on Dominion.

Teleport is getting replaced by Promote, and wards cost gold so it's all about making the expense worth it. And anyone can buy an Oracle's, if I notice I get killed in the jungle a lot on SR I get Oracle's and proceed to ward kill. But to answer your question I do think that roamers and heavy warders will make Dominion very easy on your team. But DOminion may not even have wards.

EDIT: Akali'd by Keiffeyy

no wards or tely. instead promote and some other thingy

Instead of wards they will be implementing Shaco-in-the-boxes, just without the invis. But to balance it it also surpresses anyone that walks over it for 2 seconds and it marks the target as visible on the map for 25 seconds.
