We need a new game mode on LockDown. In HardMode Style, but this time without Final Flourish (and similar), Grand Faust (and similar if you have it) and Polares (and similar).
And before they say that LockDown looks great, then why do the vast majority of Spiral Knight players dislike LockDown?
It's rare a see a random LD match going , I don't think adding another mode is a good idea these days. But for that mode, I think removing AT is better than banning those swords.
But I want Polaris should be banned imo, not only its area-denial and shock is OP and annoying, but it also causes major lags. Most players that uses this are either newbies or trolls, just one player using polaris will mostly result on other players retaliating by also using polaris. This is one of the top reason why LD matches dies, and you have to wait for decades to start another LD match.
Mist bombs are also a cancer, especially with invisible bugs... and those weapons that shocks ppls. (Its instantkills mostly if you get shocked). I think cutting the duration of the shock would be better.
