Reasoning for removal of TP, but not MP?

[Millybonk]

TP was useless, I do not understand why anyone would remove MP. If you remove MP it wouldn't even make sense.

Don't just say something without providing evidence of some sort.

TP got removed, which results in any TP class being able to spam their AoE spells all the time, which wasn't possible before.
Using that as a base it makes no sense why any AoE spell on a MP class still cost resources, right?

If the scope was to enable AoE spamming you would grant it both groups, TP and MP classes, and not just TP classes.

Most of the caster classes already could spam AoE abilities just fine. Spamming of AoE abilities is not the issue.
It is mainly healing that is limited by MP. For anything else running out of MP/TP is/was almost never an issue.

Do you actually believe that?

A test for you then:
- You as healer, a tank and 2 other TP classes at a level, when you as healer have access to a spammable AoE spell, e.g. lvl 45 as WHM to get Holy
- Tell the tank to go at an aggressive pace, but slow enough for you to have plenty of time to dps
- Cast your healer AoE-spam ability as much as possible in an attempt to keep up with the now permanent AoE-spamming of TP classes without letting anyone die
- Come back to me how long you were able to keep the AoE spamming up without neglecting healing due to AoE abilities for MP classes still costing resources

Yes, I believe it. Of course, that is based on experience from actual dungeon runs rather than contrived tests that do not match how people actually play.

Your proposed test is pointless because it misses one very fundamental point: The main role of healer isn't to do damage, but to heal. Damage is what they do when and if they have time and resources left to do so. Or in other words - healers aren't supposed to spam AoE attacks all the time because that isn't their job, while it is perfectly reasonable to for DPS classes to do so - attacking is their main responsibility.

It wouldnt make sense to remove MP because MP is a resource that actually gets used up in battle. TP wasnt with the exception of AoEs. Which was a very weird dynamic.
As I literally said above, how it functioned prior to ShB is the only classes that had trouble with resources was TP based classes when it came to AoE, where ranged TP users faired better than melee. DPS Casters did not have this problem broadly, EXCEPT if the aoe went on to long. Outside of AoE situations, TP was a moot resource, where MP has always had a dynamic use in some capacity.

Theyre just streamlining a system that didnt really utilize TP.

Look at it this way: If they streamlined TP to be on par with Mana when it came to AoE, then TP becomes a useless resource because you likely woudlnt run out of TP in AoE pulls, and you didnt run out TP in regular rotations. It would kinda just be..there.

This all being said, you can run out of mana on AoE Pulls, sure, but its not nearly detrimental. For starters, BLM pretty much doesnt have this problem. SMN appears to have quite a few spells that are AoE but dont consume resources, and its dedicated spam one is only 400 mana. Meaning you can punch that 25 times (or for a minute almost) before depleting. RDM is similar in this function. WHM still has their HOLY, which eats 600 Mana a cast, but it also has a stun attached to it along with slightly higher damage. You can spam that 15 (30 seconds) or so times before depletion. AST still has its AoE and Stellar Explosion, though its not as mana efficient as WHM in this regards. SCH is the only class that looks like its getting shafted on AoE, with only 1 aoe spell that conumes 800 mana per cast. Granted though, its always been the case with Healers that they were supposed to be balancing their damage vs healing output and managing mana around it.

The whole "They didnt want AoE" spam issue pretty much falls apart however when you see that casters didnt have a resource management issue typically, unlike the TP users. All the changes pretty much do is say "Ok, aoe spam to your hearts content. Youre gonna do it anwyays, so might as well not Gimp TP users." There's no reason to change the MP use on Casters cause for AoE its a moot issue. And unless you want melee to have TP specifically for AoE, it was gonna get axed and the solution was just make skills free cost.

Also, btw, you could justify caster mana costs simply because they sit at ranged and are less prone to risks like cleave or close aoe which are fairly common.
