As you know, there are some guilds that abuse this mechanic in their favor and go extreme bunker.
This allows them to be extremely tanky and kill blobs without any skill or effort.
The builds consist of sharing buffs that allow party members to siphon life from enemies.
The siphoning carries them over without effort or any skill what so ever and the life siphoned keeps them alive without even using their healing skills.
Anet needs to remove or rework how life siphoning works to stop those guild abusing game mechanics.
They have realized that life siphon goes through damage mitigation skills and it has no restriction what so ever.
These damage mitigation skills are completely useless against the life siphoning abusers.
The simplest solution will be to restrict life siphoning by not making it a share buff, and by only allowing the attacker to steal life.
