A sienna using melee 90% of the time is something that not even unchained will do. There’s supposed to be a fine line between going ranged and using melee. That’s the point of battle mage, that’s why unchained exists, and that’s why pyromancer, Siennas most ranged focused class, still has numerous talents designed to help her melee.
That’s why things like shield of tam and, to a lesser extent, dissipate exists. The phrase is intent vs execution. It’s obvious what the goal was and what it ended up being. Sienna’s can use their staff to kill storm vermin, berserkers, and entire hordes with impunity, heat management is nonexistent and inconsequential which allows you to use your close range alt fire instead of your melee weapon. These things may have been designed to be strong, but there is a serious breakdown somewhere in the process that titled it from strong to arguably overpowered.
Again, intent vs execution. They clearly didn’t want conflagration staff to be bad. They didn’t want fireball to be nigh unusable due to it’s splash. They certainly didn’t want melee to feel like it’s only job during hordes is to sit still and let Sienna handle everything (on champion). And they may not have even intended for it to be able to one shot stormvermin. We’ll never know.
What you’ve explained here:
is called the path of least resistance. Players will always cling to the easiest way to handle something. No part of that confirms that it’s the way things should be.
Regardless, all we need FS to say is “yes this is how things are supposed to be” or “not this wasn’t what we wanted this to be like” and you’ll have these conversations squashed. But as with saltz having his killing potential tuned all the way down, I imagine that the answer to this debate will likely be one you’re not going to be happy with.
The only reason it’s not an even bigger problem than it could be to me is because I do nothing but Legend, often in the morning and the number of Siennas I run into are lower than what I would get if I played Legend during the evening or (heavens forbid) champion.
But don’t think for a second that it’s fun for anybody else to have no ability to kill things coming into a chokepoint or even in open fields because they all die before you can get to them.
Edit: After rereading this I should note that I don’t think it should be nerfed out of the ability to do the damage it does. Rather I really think heat needs to be looked at both for her and IB.
