For those who don't know what a spiker team is:
A spikerteam is made out of mostly rangers, aeromancers or blood necros. Most of them have teamspeak (they can hear their leader talk, don't ask me how it works) and they pick a target, like a monk or ele. The leader counts down and all partymembers attack the same target at the same time, causing massive damage and killing it before the enemy monk can even react. Also, they use Frozen Soil so dead players cannot be ressed as long as that spirit lives.
I think this is quite unfair and i hate running into a team like this in the arena. Arenanet has made efforts to make spiking less effective but there are still plenty teams like these around. See for yourself in the observe mode!
Keeping things fair, i'd rather not start a spikerteam. Lets just hope we dont get to fight any.
