Red mage and Time mage aren't competing for the same spot in the least and I'm unsure why so much argument about it continues. I'm not going to go into depth about the differences I'd suggest going back and playing some old games.
If anyone had read the post I linked to (Foolish I know) I stated I fully anticipated other jobs way before Time Mage.
As for people declaring stuns(stop), hastes and reflects are too OP that is kinda small minded(Almost an old Tanaka we can't give them anything mindset) Stop can be just a couple of seconds to stun enemies, Reflect could be a quick cast long cooldown spell used in tricky situations to help a tank out if an enemy is about to land a huge spell (Not all the damage has to be sent back to them just a percentage of it) As for stop alot of bosses could just be immune to it, remember back in the day when old FF bosses were randomly immune to a ton of enfeebling magic?
One way I see Time Mage being implemented would be a crowd control support job.
For instance you're in a dungeon there's a large group of enemies have the Time Mage cast Gravity on them as the tank pulls out one or two to fight without gravity on them, then he casts Haste on his party and slow and Age(Old) on the enemy (to decrease their attack speed and lower their stats over time), then some of the gravity'd enemies get closer so he binds them giving the party more time to take on the mobs. Maybe he even has a long cooldown expensive magic spell like Comet to deal some damage every other battle or so. Maybe they were fighting Bombs, and while the Bomb was casting self destruct the Time Mage used Stop to momentarily stun and prevent the blast from ravaging your party. Maybe someone had to leave and you invited someone new and had the Time Mage spawn a portal at their location to pick them up.
I mean these are all things possible and being done in other games, nothing is game breaking nothing encroaches on other jobs.
EDIT:
Oh yeah? Corsair/Musketeer is a traditional Final Fantasy job? Since when? Enlighten me. As for all the coloured mages I agree we need them all in the game, as for my post I stated I fully expected and anticipated Thief, Ninja and Samurai to be implemented first (With the lack of Thief being a grievious Final Fantasy sin in my opinion. How many main characters were Thief? A ton.)- While some people are ignoring the fact that I have stated multiple times, that if done correctly, the job may be viable and wouldn't disagree with implementing it, however taking priority over more traditional FF jobs is blasphemy. The jobs I am talking about are: Red Mage, Dark Knight, Blue Mage, Corsair/Musketeer, Thief, Ninja, Samurai.... To name a few.
Warps, and Teleports are utility, and since when has anyone cared about classes not having utility, there is practically none of what is known as traditional MMORPG utility in FFXIV or FFXI at all. Utility is generally none combat. As for float that could also be considered a utility (Slow fall) however I don't see a use for it and didn't list it since we will only be jumping over small little cliffs.- The spellset that was listed, has very little utility in it's original, FF lore form, if it is not already tied to / can be given to other jobs.
