Instead of trying to act like giant flurry or drum spec berserker who can simply go out, bloodthirst and fight group of 3 pretty succesfully without even doing much.
Dark-elf stsf should play like a shaman ... who has to fight a bit .... then run away to heal ... then fight again ... and so on.
It is MUCH MUCH MUCH harder thing to do and is simply next level of the personal skills of the player. When you can play combos like dark-elf stsf, shaman, often druid, often bard, defenders in the village, maybe something else with healing - like defensive shapeshifters.
But if you play berserker stsf it is already a fail from the begining. But can be doable with some success - and even with pretty big success because of the berserker's powers.
It is my personal opinion though.
