i already see your case 3 healers vs 2 healers, and the 3 healers was down before.
1 healer is not enough, i already see case when 1 healer was enough but only when they don't focus him too much (it's what happen when players aren't focus a solo healer...)
I just mean even in frontline many group will plan to kill healer first, and loose healer can mean loosing in most of the case.
That's why i don't understand the fact : wolfden is game when we have to kill healer first, it's obvious without healer you lack in heal in any content of the game XD.
