Koschei doesn't need a nerf, the enemy team just needs a brain. Purge, drain, armor break etc.
I could not possibly agree more with this. As it stands, one or two good players with the right loadout can break a Koschei with ease. There's no need to make it effortless.
Pretty much this.
The Koschei nerf, showing both a striking disregard for the games balancing (The Koschei is fine in a balanced T4 game) and the games' real issues (balanced T4 games rarely ever happen) was kinda the last straw for me, showcasing that they fully intend to drive this game into the wall.
After a few weeks of the "Koschei OP" meme, most people have adapted to it. Knowing its weaknesses, killing a Koschei is almost trivial. But they would rather gimp the games only actual healer (as in: can keep people alive in a fight, not just idly regenerate them in cover), than promote some better tactical play or, god forbid, decent matchmaking.
The one thing I will concede to is that Koschei point generation is pretty insane (only ship I ever got a 5-figure score with), but that was balanced out by the fact that healing barely produces any ribbons, and thus hardly any money. Playing my corvette I would usually cash in similar amounts with half the score.
