ya it is different the horde have a feast the alliance address there people who would have lost far more as the alliance lead the war on the legion on almost every front. the night elf's lead in val'sharah the humans lead on the broken front the wargon lead in stormheim and the goats lead on argus. while the horde only had a presence in stormheim. the alliance gave alot more to the war and would lost alot more addressing the people who would have lost alot more love ones makes more sense then having a feast.
