I dont know about everyone else, but one thing I seriously miss is PoM pyro spec for PvP. Not exactly the BEST spec for pvp, seeing as how your spec only served its purpose every 3 mins, but it was a very fun spec to BG and Arenas with.
I also think that Pyroblast is in need of a buff. The 5 sec cast time spell, which you need to spec for, cant even crit more than a FFB Fireball or Arcane Blast in most cases.
Pyroblast used to be a mages cool and different spell that they had that did what it was supposed to..but now is overshadowed by each of the specs Primary Spells. Think the talent is outdated, tbh.
But aye, finding a way to bring back PoM Pyro would be great. It was removed because why...How ridiculously OP arcane was in the 1st few months of WOTLK, 95% because of the stupid amount of dmg Arcane Barrage could do.Was always loads of fun playing and watching youtube videos of players using the spec. It guaranteed a good time.
