There seems to be a large number of people who think the minority of people who can beat Basalt are what the metagame is about. As much as I'm sure that thought would appeal to you, it's fundamentally flawed. Rule changes should always be made for the better of the majority - and the fact of the matter is the majority are abusing Basalt and making it much more difficult for the minority and everyone else in the majority, which then forces those players to conform or stay home.
The amount of "well everyone else should train and learn to use attack types" idealism going around is pretty upsetting, since reality should be considerably more apparent to people. You don't make rules based on an idealized version of the metagame, you make rules based on the reality of it.
90% abuses it, 10% knows how not to. You never, ever vote in favor of 10%, if you're really trying to promote a healthy, happy, enjoyable metagame for everyone in the fandom to participate in. It's a basic logical fact, which is admittedly all I can really point out here, given my limited experience.
Yes, some people will decide to quit because they can't use Basalt. And yes, other people, if Basalt stayed in play, would learn how to beat it. On the other hand, most Basalt users would move on, and a lot of people likely already avoid some events because of Basalt's current usage.
It's not worth leaving the meta in ruins for the sake of teaching ten or twenty people to beat Basalt.
Keep in mind this is all from the viewpoint of someone getting into it that DOESN'T want to take the easy way in or out; I've been practicing nonstop since I got my MFB, researching combos, which parts are prone to breaking, etc. And I do intend on getting to the point where I can beat Basalt with certain combos - possibly even reliably. However, that point is a long way off for me.
