Part 2:

Scholar should get removed/reworked under this concept and replaced with Dancer as a Healer Job Line and be used only in the story temporary for Alisae, until she changes to Redmage when she gets the rapier

Job Level 1 = Performer = Max Level 50
Job Level 2 = Dancer = Max Level 70
Job Level 3 = Swashbuckler = Max Level 80
Job Level 4 = Harlequin = Max Level 90
Job Level 5 = Dervish = Max Level 100

Blue Mage should become the games Joker Job, which should adapt to the situation based on using fitting Monster Skills

And lastly should get added as new tank job line this, using instead of books now Gloves (Magic Gauntlets, which can basically share the skins with Fist Weapons, but are just for Magicians instead of Warriors)

Job Level 1 = Scholar = Max Level 50
Job Level 2 = Mesmer = Max Level 70
Job Level 3 = Dreamcatcher = Max Level 80
Job Level 4 = Illusionist = Max Level 90
Job Level 5 = Time Mage (Chronomancer) = Max Level 100.

Now you may ask, tanking without heavy gear and no shields ect.? You will jiust see, hoe powerful Time Magic is for basicalyl tanking and negsting anything, that actually happened, making it in an instant unhappen again through powerful Health Regegenrations by turning back the time, supprting the party with Haste, and slowing foes, thus decreasing their DPS, what makes in return tanking alot easier, or create with the help of Time magic illusions of your self and clones, that catch up damage for you instead and help in tanking masses of enemies, keeping aggressivity on you.
Chronomancers are the perfect Magic Tanks that this game is missing. So far we have only 2 physical tanks, its time for a magical one now.
