That idear is good there is only i think 5 farming places, but we must remember that this realm is rather new, Ek should (and im sure will) go all the way to hero ek 7, I think it would be nice to have separate farming places.
I was thinking of adding EF (Old grinding instance) and the warglaives upgrades, but as someone els has said up the stats on them a bit,
I think they are adding frostmourn but I think they should not add it yet, start with warglaive like the old times, and add EF to farm for glaive, (easy to kill the monster but must kill 100's of them) then at a high rank it changes to frostmourn then you farm for frostmourn (make it a diffrant instance)
As for heroisum>sunset>courage gear, i think they should be vote point items, Add heroisum to the Vote vender (about 10 votes a peace depending on the stats),
then use upgrade gem on it, id say add a new world boss (menchaned in a other thread) that drops items to upgrade them (kinda like what BA is doing ATM,) The boss i think should be like WOS (will of sargares) and then for courage, We must have to grind to get it.
