Fix warden meta.

[Kingsbounty]

Hi. Warden in this last patch is very op when someone stack it for teamate and it hold almost every levels. The problems is that,when they stack warden for teamate they run to teleport area after killing and then they all will be at mid. This so unbalance pls fix thid teleportion area that stacking units by teamate dont teleport mid.
Wardens, Thunder birds, furbs and most melee units teleport mid by stack on teamate..
Sry for bad english.
