For context(All at tier 4): The average stats of Attacker mechs is 18km 36,600Hp, though all other attackers have 32 top energy.

They should have just done away with the tiering system entirely and tried to instead to bring everything to a relative balance. There's going to be more updates that directly or indirectly affect the viability of mechs and weapons to different degrees and over time it will again be less intuitive. There's not a lot you can do about that except update the grade of items over and over.

There's always going to be some items that are better than others. But it used to be that there wasn't such a big difference between the best items in the game and the rest, with few exceptions. Now that's not so true, and unfortunately it seems devs are leaning even further into that. Which can really only mean pay to win ahead. Some mechs now might just have no hope for a buff. It feels really shitty because sticking true to a tiering system feels like the devs are pointing at some mechs and saying "don't bother using these guys" which just overall makes the game less fun.

It's definitely one of if not the most powerful mech in the game. It doesn't really shine until R6, but it's one of the highest priorities to max. With DL12s it can easily rack up 600 or more points per tournament match. Hasn't really been popular for EMR12s, but I know one skilled player who runs it in tourney and just heals all match while annihilating the other team.
