BLM could use some button consolidation

I can't agree with this. Scathe doesn't cost Polyglot so there are definitely times I'd rather use Scathe than Xenoglossy. Using Scathe is far better against weak or underleveled enemies, or enemies with a fraction of HP. Being forced to use Xeno in those situations would be a complete waste and feel horrible.

If a Scathe would kill them, then so would any other attack from your party members. Just wait 1 second.
Might be a niche use in dungeons, but nothing essential and there's no pressure to save those couple seconds.
In a trial/raid setting, absolutely useless.
