Well doesnt it belong to Final Fantasy (offline titles as well) that every mob has its element weaknesses? which i think is an interesting factor and makes it special.
The PROBLEM is.. since they switched the skills and left one element completely out is.. that you have in each situation only one mage with the right element.
in FFXI the BLM has access to ALL Elements.. he can switch easily to any element depending on the enemy he attacks.. the same with the conjurer in FFXIV pre 1.20 where he had all elemental spells.
and the thm had light and darkness which are almost outside the elemental wheel.
that was really balanced. but now we have a really inbalance. conjurer has just 2 elements.. and the blm just 3. and one is totally missing..
splitting that many elements on two or three mage classes is not a good idea with these elemental weaknesses of the mobs. i think i would more shout for.. switching all elements over to blm and give whm the lightspells back.
sounds boring .. but it seems weird to me, to split the elements into two or three classes
and as a blm you spam thunder most of the time... (ice is mostly useless in damage)
