I pretty much agree with nothing in the OP or at least with very few. I am especially tired about the obsession with Smiter and character xyz should have Smiter. Your argumentation in that context is perplexing. You say she is a tank career. However, if we look at two other tank careers (IB and FK) you see that they are usually used as crowd control units which have stagger and THP talents mirroring that. Which means that Unchained should NOT have Smiter if she is meant as tank/crowd control.
Giving Unchained Famished Flames is a bad idea as well, since it drives her more to a staff using career. She already has options where she can be played range heavy, she doesn’t need Famished Flames on top of that which would damage her melee play because it makes Fire Sword broken. Actually, for that last reason no Sienna careers should have Famished Flames because it cripples melee choice (example: what do you think is the percentage of Battle Wizard’s NOT using Fire Sword?).
Also Lingering Flames should not exist in its current form. There should be not time unlimited in the game. Period. Make it longer twice or thrice but not unlimited. And it should not damage superarmor!.
Making Volcanic Force a passive has to be some bad joke as well. Battle Wizard is already nuking everything left and right, why should she be buffed. I agree that the tier 2 talents need replacements but just because in their current form they break the game on different levels (hyper-synergy on Fire Sword, unlimited cheese).
If you want to give her more “personality” then:
- Let Unchained as she is with a melee/support-orientation and large flexibility; if you have to change something switch Abandon and Chain Reaction because it makes sense balance-wise
- Reduce the melee crit from Pyromancer in a way that you get 20 % at max (actually no career should have a crit chance above 25 %) and make her more ranged focussed
- Reduce the dps output of Broken Wizard all over the board but increase her stagger and area denial abilities, let Battle Wizard the career which CONTROLS the battlefield but WITHOUT leveling it to gorund zero
This way you will have a melee/support-orientated class, a range-orientated class and a control-orientated-class. People will just have to let go of melee-crit Pyromancer and Broken Wizard.
