@Enigma i feel your pain, I really do.
But while obviously the MW:LL title is somewhat miss leading, it is still how Mechs go about combined arms game.
So far the dev team merely completed (or is about to) what the original devs had in the work pipe line - nothing more.
And while there is still more work to be done, the game is still away from what all the original team had in mind.
I assure you, the balance is also way improved over what we had back then (0.7.1 era) and we are rid of many builds that caused cancer and rage quit among many a player...
I agree with you the game is quite more taxing on the nerves than any other title I ever played. It it is planed to be even more so.
The ASF, that where a niche back then, are a class that can be used (and enjoyed) by players now - ASF vs ASF dogfight is out of scope of the game development team, everything else is fair game.
The BA are midst a extensive rework, and are broken somewhat by the time - it is known by most of the active community - but they have hard counters one can use for the time still...
One can't simply get in a public match right now and be "master and commander" any more - the game grew complex, one has to read the wiki guides, explore play styles and work on his own - tactics, strategy and skill included.
This is partially due to having players with year long mileage with this game, and a healthy influx of quite competitive and able layers from other MW titles as of recent.
If you are back, welcome back, if you are new, welcome to the most special battle tech game yet.
This isn't a git gud rant, I genuinely appreciate your concern and invite you to Discord to take part of the community voices and efforts to get the most fun we can.
