Could you elaborate on things you found worse in AoE2 HD vs the original?
I've never played the original, but I'm a huge fan of the HD release and all of it expansions.
It's laggier and has desync issues. Not just me but commonly experienced by streamers I watch and frequently discussed on /r/aoe2. Voobly has a much better experience. Worth checking out, particularly if you're any good.
