LoS on trees and the like
Pretty simple suggestion:
Bring back the LoS on objects (trees etc) that was recently removed on Icecrown. Regardless of whether this is blizzlike or not, the removal of LoS from these objects has been a huge downgrade to the quality of the server; not only does it feel much less immersive (it feels broken and cheap quite frankly) but it has also completely unbalanced PVP outside of arenas.
I realise the server is intended to be blizzlike, but transmog in WOTLK certainly isn't and neither are the pvp honor kill titles. Strive to be better, not the same.
