Gonna counter some of these points.
1. Metas will always exist. There's no point into bringing this into the conversation as its just an inevitable outcome with games. You ignore that not everyone follows this meta, especially with blue mages.
2. You fail to realize that blue magic is a thing in previous FF games and its spells and effects were done to be as closely translated into FFXIV as possible. This is the sole reason why its limited with current content only, so that veterans and players can have keep the integrity of the unbalance of the class. You cant have a White Wind that doesnt heal based on your HP's values, because every other FF game that has that spell thats what the intended effect is supposed to be. Dumbing the blue magic spells down kills the whole point and appeal of blue mage and funny enough the fact that you're trying to do this, is the same level of thinking for why we have the 2-minute meta homogenization existing in the first place. Congratulations Zebraoracle, if I didnt know you any better, you're rocking the same boring wavelength as the actual dev combat team.
3. Again, you are failing to realize the whole point of Blue Mage. Blue Magic itself isnt supposed to be balanced nor limiting. You're saying that in order to make Blue Mage not limited...is to actually cut the meat and potatoes on why the job is fun to play. Nobody is going to want to play a neutered class. We have seen countless examples of the audience complaining about their jobs further being streamlined to fit into the "meta" agenda, therefore making it worse.
Blue's potential is already here in this game. The points you are proposing here are EXACTLY the opposite of giving the job its creativity. It baffles my mind how you're not even hearing yourself telling me that in order for Blue Mage to be amazing and creative...it needs to be further limited?
