First of all, Deathwing's Cataclysm caused a tidalwave that wiped out Southshore.. Forsaken only mopped up the last few souls..
Second, Hillsbrad was NEVER Alliance territory.. It was Contested, but HEAVY HORDE BASED (18 alliance quests vs 100+ horde quests).
Gilneas is NOT a Horde levelling zone.. It's an EMPTY zone.
Please change your sig to this:
Kaleredar is WRONG!
