Post-reset, suddenly all sorts of 'n00bs' took over the game, armed with smartphones and taking all the top spots. Especially Burn was a little sour about that... And still likes looking back to his glory days
HMW has become all about the missions nowadays. A bug in the Arena makes it impossible to see a result of a matchup. Missions are tough for lower levels, but with quite a few players now having team members at level 8, 9, 10 and even 11, if you get a hit or a repair in against one of those guys, you're pretty much set, even at a low level.
In fact, this is a huge benefit of only starting again now: after the reset, the startup of the game was extremely slow due to no high levels being available. Nowadays, a high level player can easily net 1,000,000 xp a day for his team.
Alt mdes are still important. Strafe and repair have once again become the best skills to have, even more so than Ram used to be (considering one-on-one Arena fights are no longer viable). At the high levels, I guess we still see a lot of the same faces, although the top 8-12 players all seem pretty active... And I don't think there really is one super HMW powerhouse robot: the top 10 'bots are all well matched, even with a level spread from 9-11.
And the super-weapons from the past have been neutered: Battleblades are good, but not amazing, as are Dol-Lazers.
