that rod in lock was so-so in wild…technicly an enabler to puke hand for opponent to use board removal
the demon seed quest however was a major issue
Loatheb is much more concerning as it block board removal entirely
as for Standard…i dont think warlock get enough synergy from the discount…far from the wild level(which wasn’t problematic in wild(Rod))
EDIT: the other stuff you pointed out however…yes they’re an issue
