Resting after a Battle/Fight.

Hello, I often try to watch the Devstreams for AoC but don't get to involed or look too deeply as I don't want to spoil to much of the game for myself and just want to look forward to playing it. However mostly seen in the recent Devstream on Feb 29th I noticed something that rather puts me off and would like some more information and to just give my feedback on, as I can't seem to find any recent information or questions/answers regarding it. Question: After a big fight or any fight/battle to where your Health/Mana have dropped below say 30% you are now at a point where you need to "sit" and just wait for your Health/Mana to be restored, is this going to be how it is going forward and on release? I feel this is an old school mechanic and just doesn't fit AoC or many MMORPGs to this day and it's an outdated mechanic. This is something I saw when I first played Aion Online after it's release and after a single fight/battle of 1-2 mobs I would sit down for 5-10 minutes (everytime) to restore my Health/Mana as Potions were not easy to obtain. The issue is that I don't see Consumables being used in a fitting way or seem to be a 1 time thing and that's it. I just don't see the point of this "sitting down" to restore oneself an ideal or fun mechanic. Example: I just finished a battle/fight and now below 30% Health/Mana now comes along another player and kills me. Doesn't sound very fun for either side nor does the idea to sit and wait for 5 minutes staring at my screen doing nothing.
