What change do you want to see on your main class for Endwalker ?

need more buttons on my keyset for Blm aethermanipulation macros (need 7, one for each player to target xD)..
... so just simply F3 & F4, B3 & B4, LL & BTL each on one button..
... don't change any thing else on Blm (its perfect as it is)
... if need to add some thing new, increase flat damage (not just SS) when standing on LL for all caster (healer) party members (just make the LL bigger), make flares have a chance to proc a "free, no mp needed flare", and maybe add a new flashy Blizzard move, that does extra damage, if target has a thunder dot (but can only be used once per rota, like Despair)

While I don't agree that BLM would necessarily be perfect with just these changes, given that one can't use the latter of each pair without first casting the prior, and there's never a reason (at least since the quick-cast bug was removed in early ARR) to double-cast F3 or B3... sure, these button-efficiency changes sound great.

Or, at the very least, make LL-BtL and F4-B4 optionally the same button. If you place both from the hotbar, they remain separate. If you remove either from the hotbar, their keys return to dynamic dual-function keys.
