since this pvp patch has been a little bit silly, I wanted to get a little bit silly too myself, behold, my incredibly balanced pvp change ideas:

Pre 7.1 Salted Earth effects gets added to Mesotes w/ unpurifiable bind

Afflatus Purgation becomes Mass Polymorph from DnD

Marksman Spite is replaced with summoning a Rival Wings Brute Justice and getting in it
Soul Resonance is replaced with the PvE blm lb3 Meteor that instakills everyone in the radius after the telegraph

Eventide is replaced with summoning an army of Fray clones that assist you in battle
Summon Bahamut now brings Dalamud down to crush your target before unleashing the primal
Relentless Rush now gives you a second gunblade (this will halve your recast timer)
Zantetsuken -> Omaewo Shinderu (kuzuchi requirement is removed)

Meteodrive is now replaced with a boost that gives you -90% recast timer

Tenebrae Lumerum is replaced with an lb that sends target straight to the 13th for 1 minute
