I can tell you, as someone who played it back on live before and after it's nerf and who played it on Homecoming before and after it's "Buff", it's different now. Not everyone will get the same mileage or enjoyment from the re-envisioned Energy Melee set. If a player dislikes combo mechanics, chances are they will dislike the new energy melee.
Tanks.. there is a can of worms. They did get an increase to number of targets for many attacks which = more damage over all. Raising aggro caps slightly, maybe.
The Homecoming team has done a good job to allow the game to function well on modern computers. For that and making the game available, they deserve kudos.
@Sapharan Lots of other options available which may replace some of those old favorites. Still lots of fun to be had if you missed the old game.
