I disagree, the elemental lock-out is a definite intended risk factor.

While I can agree with the sentiment, it feels like most fights play out way too quickly for an elemental timing out to be a thing that happens in situations outside of stylish/crazy PVE, and spending almost half your sp to buy all the enchants, not to mention dedicating the skill slots to have them on-hand, is missing you out on a lot of options already. Why not just increase the weakness a little, or inflict some sort of debuff or damage for trying to overwrite an enchant with its opposing element?
