We're well into Onxyia patch 3.3.2 -- and it seems every bodies enjoying the revamped instance. I'm glad to see old content re-glorified, as I love a lot of the old fights and this lovely instance filled a gear gap I was having in replacing my spell power weapon- and lets be honest, there is a lot of old models that look great and are dis-used right now.
Can an old Worgen learn new tricks?:
We know almost definitely that Blizzard are implementing 'Heroic' Deadmines and Shadowfang Keep, with new armour but same bosses and similar story lines-- the question is, will it work?
I think so, Yes. I love almost all of the old content, and can't wait to spend more time in Azeroth, its so vast and beautiful, but un-used once your high level. Think of it as a business investment, a local area is low on tourism, you're going to try and attract people-- maybe Deathwing is doing Ratchet's local stores a favour.
But the most interesting thing is if they decided to go one step further and keep making old instances have heroic modes, and if they do, I'd support them 100% of the way. Its a great way of offering low and high end content that people really enjoy and would love to see in two different perspectives (I mean, how awesome is it going to be beating Van Cleef to death with bigger, better abilities!).
I'm not sure what other peoples thoughts are on this, but I certainly welcome any more old-content republishing Blizzard have in store.
