I am unsure if there is any information out on this...
I normally play supporting characters (heal/buff) in mmo's and i am wondering how buffs will be handled in ESO.

Will it be spot/party/proximity based?

Spot - Select target + apply buff
Party - Join party + apply buff + affects entire party
Proximity - apply buff + affects allies that are close enough to you

And how long should such buffs last?

If i had to guess i would say its proximity based and probably only for 2-3 minutes?

Can anyone confirm/deny or is this a wait and see type of thing?

Thanks!
