That would definitely be a pretty good idea for those remaining legacy players out there. And i know that this have been mention a lot of times, but wouldn't it be great if there is like a SuperMechs Legacy or something like just a seperate minigame or something inside the current SM. But as far as i know there are still many peeps like me (probably) who loved the older version of SM.
If you think about it, there really isn't that much strategic battles in the current SM. I mean just look at CleverName, basically winning all his arena or other matches by completely overpowering the enemy (from watching his replays) (and please dont take this as any offensive means, i am just trying to give an adequate example). In terms of combat, the current version of SM is more about collecting items, see who have more L-Ms, who upgrades and max things out faster, and completely overpowers the enemy instead of actually using our brain. Especially considering the fact that pay-2-play players have a much higher chance of winning due to the higher chance of getting good items.
In general, it'll be great to be able to bring back the old version of SM as it will be much more ... "educational??" (maybe since strategic war requires more brain cells).
